## Overview
2014-07-12 07:34:47 +02:00
2017-06-14 07:13:05 +02:00
Bootstrap's form controls expand on [our Rebooted form styles]({{ site.baseurl }}/docs/{{ site.docs_version }}/content/reboot/#forms) with classes. Use these classes to opt into their customized displays for a more consistent rendering across browsers and devices.
2014-07-12 07:34:47 +02:00
2017-06-14 07:11:44 +02:00
Be sure to use an appropriate `type` attribute on all inputs (e.g., `email` for email address or `number` for numerical information) to take advantage of newer input controls like email verification, number selection, and more.
Here's a quick example to demonstrate Bootstrap's form styles. Keep reading for documentation on required classes, form layout, and more.

## Form controls
Textual form controls—like `<input>`s, `<select>`s, and `<textarea>`s—are styled with the `.form-control` class. Included are styles for general appearance, focus state, sizing, and more.
Be sure to explore our [custom forms](#custom-forms) to further style `<select>`s.
2018-03-14 16:44:38 +01:00

{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
For file inputs, swap the `.form-control` for `.form-control-file`.
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<form>
<div class="form-group">
2017-06-14 07:11:44 +02:00
<label for="exampleFormControlFile1">Example file input</label>
<input type="file" class="form-control-file" id="exampleFormControlFile1">

{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
### Sizing
Set heights using classes like `.form-control-lg` and `.form-control-sm`.
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm">
2018-03-14 16:44:38 +01:00

{% capture example %}
2017-06-14 07:11:44 +02:00
<select class="form-control form-control-lg">
<option>Large select</option>
</select>
<select class="form-control">
<option>Default select</option>
</select>
<select class="form-control form-control-sm">
<option>Small select</option>
</select>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
### Readonly
Add the `readonly` boolean attribute on an input to prevent modification of the input's value. Read-only inputs appear lighter (just like disabled inputs), but retain the standard cursor.
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<input class="form-control" type="text" placeholder="Readonly input here…" readonly>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
### Readonly plain text
2017-06-14 07:11:44 +02:00
If you want to have `<input readonly>` elements in your form styled as plain text, use the `.form-control-plaintext` class to remove the default form field styling and preserve the correct margin and padding.
2017-06-14 07:11:44 +02:00
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<form>
<div class="form-group row">
<label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
<div class="col-sm-10">
<input type="text" readonly class="form-control-plaintext" id="staticEmail" value="email@example.com">

2018-05-21 00:10:31 +02:00
## Range Inputs
Set horizontally scrollable range inputs using `.form-control-range`.
{% capture example %}
<form>
<div class="form-group">
<label for="formControlRange">Example Range input</label>
<input type="range" class="form-control-range" id="formControlRange">
</div>
</form>
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
## Checkboxes and radios
Default checkboxes and radios are improved upon with the help of `.form-check`, **a single class for both input types that improves the layout and behavior of their HTML elements**. Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.
Disabled checkboxes and radios are supported, but to provide a `not-allowed` cursor on hover of the parent `<label>`, you'll need to add the `disabled` attribute to the `.form-check-input`. The disabled attribute will apply a lighter color to help indicate the input's state.
Checkboxes and radios use are built to support HTML-based form validation and provide concise, accessible labels. As such, our `<input>`s and `<label>`s are sibling elements as opposed to an `<input>` within a `<label>`. This is slightly more verbose as you must specify `id` and `for` attributes to relate the `<input>` and `<label>`.
2017-06-14 07:11:44 +02:00
### Default (stacked)
By default, any number of checkboxes and radios that are immediate sibling will be vertically stacked and appropriately spaced with `.form-check`.
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<div class="form-check">
<input class="form-check-input" type="checkbox" value="" id="defaultCheck1">
<label class="form-check-label" for="defaultCheck1">
Default checkbox
2017-06-14 07:11:44 +02:00
</label>
</div>
<div class="form-check">
<input class="form-check-input" type="checkbox" value="" id="defaultCheck2" disabled>
<label class="form-check-label" for="defaultCheck2">
Disabled checkbox
2017-06-14 07:11:44 +02:00
</label>
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<div class="form-check">
<input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios1" value="option1" checked>
<label class="form-check-label" for="exampleRadios1">
Default radio
2017-06-14 07:11:44 +02:00
</label>
</div>
<div class="form-check">
<input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios2" value="option2">
<label class="form-check-label" for="exampleRadios2">
Second default radio
2017-06-14 07:11:44 +02:00
</label>
</div>
<div class="form-check">
<input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios3" value="option3" disabled>
<label class="form-check-label" for="exampleRadios3">
Disabled radio
2017-06-14 07:11:44 +02:00
</label>
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
### Inline
Group checkboxes or radios on the same horizontal row by adding `.form-check-inline` to any `.form-check`.
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1">
<label class="form-check-label" for="inlineCheckbox1">1</label>
2017-06-14 07:11:44 +02:00
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2">
<label class="form-check-label" for="inlineCheckbox2">2</label>
2017-06-14 07:11:44 +02:00
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" id="inlineCheckbox3" value="option3" disabled>
<label class="form-check-label" for="inlineCheckbox3">3 (disabled)</label>
2017-06-14 07:11:44 +02:00
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1">
<label class="form-check-label" for="inlineRadio1">1</label>
2017-06-14 07:11:44 +02:00
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
<label class="form-check-label" for="inlineRadio2">2</label>

</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3" disabled>
<label class="form-check-label" for="inlineRadio3">3 (disabled)</label>
2017-06-14 07:11:44 +02:00
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
### Without labels
Add `.position-static` to inputs within `.form-check` that don't have any label text. Remember to still provide some form of label for assistive technologies (for instance, using `aria-label`).
2017-06-14 07:11:44 +02:00
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-06-14 07:11:44 +02:00
<div class="form-check">
<input class="form-check-input position-static" type="checkbox" id="blankCheckbox" value="option1" aria-label="...">
2017-06-14 07:11:44 +02:00
</div>
<div class="form-check">
<input class="form-check-input position-static" type="radio" name="blankRadio" id="blankRadio1" value="option1" aria-label="...">
2017-06-14 07:11:44 +02:00
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-05-27 23:38:37 +02:00
## Layout
Since Bootstrap applies `display: block` and `width: 100%` to almost all our form controls, forms will by default stack vertically. Additional classes can be used to vary this layout on a per-form basis.
### Form groups
The `.form-group` class is the easiest way to add some structure to forms. It provides a flexible class that encourages proper grouping of labels, controls, optional help text, and form validation messaging. By default it only applies `margin-bottom`, but it picks up additional styles in `.form-inline` as needed. Use it with `<fieldset>`s, `<div>`s, or nearly any other element.
2014-07-12 07:34:47 +02:00
2018-03-14 16:44:38 +01:00
{% capture example %}
<form>
<div class="form-group">
<label for="formGroupExampleInput">Example label</label>
<input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input">
</div>
<div class="form-group">
<label for="formGroupExampleInput2">Another label</label>
<input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input">
</div>
</form>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
### Form grid
More complex forms can be built using our grid classes. Use these for form layouts that require multiple columns, varied widths, and additional alignment options.
2018-03-14 16:44:38 +01:00
{% capture example %}
<form>
2017-06-14 07:11:44 +02:00
<div class="row">
<div class="col">
<input type="text" class="form-control" placeholder="First name">
</div>
<div class="col">
<input type="text" class="form-control" placeholder="Last name">
</div>
</div>
</form>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
#### Form row
You may also swap `.row` for `.form-row`, a variation of our standard grid row that overrides the default column gutters for tighter and more compact layouts.
2018-03-14 16:44:38 +01:00
{% capture example %}
<form>
2017-06-14 07:11:44 +02:00
<div class="form-row">
<div class="col">
2017-06-14 07:11:44 +02:00
<input type="text" class="form-control" placeholder="First name">
</div>
<div class="col">
2017-06-14 07:11:44 +02:00
<input type="text" class="form-control" placeholder="Last name">
</div>
</div>
</form>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
2017-06-14 07:11:44 +02:00
More complex layouts can also be created with the grid system.
2018-03-14 16:44:38 +01:00
{% capture example %}
<form>
2017-06-14 07:11:44 +02:00
<div class="form-row">
<div class="form-group col-md-6">
<label for="inputEmail4">Email</label>

Create horizontal forms with the grid by adding the `.row` class to form groups and using the `.col-*-*` classes to specify the width of your labels and controls. Be sure to add `.col-form-label` to your `<label>`s as well so they're vertically centered with their associated form controls.
2017-06-14 07:11:44 +02:00
At times, you maybe need to use margin or padding utilities to create that perfect alignment you need. For example, we've removed the `padding-top` on our stacked radio inputs label to better align the text baseline.

#### Column sizing
As shown in the previous examples, our grid system allows you to place any number of `.col`s within a `.row` or `.form-row`. They'll split the available width equally between them. You may also pick a subset of your columns to take up more or less space, while the remaining `.col`s equally split the rest, with specific column classes like `.col-7`.

2017-06-14 07:11:44 +02:00
#### Auto-sizing
The example below uses a flexbox utility to vertically center the contents and changes `.col` to `.col-auto` so that your columns only take up as much space as needed. Put another way, the column sizes itself based on the contents.

You can then remix that once again with size-specific column classes.

### Inline forms
Use the `.form-inline` class to display a series of labels, form controls, and buttons on a single horizontal row. Form controls within inline forms vary slightly from their default states.
- Controls are `display: flex`, collapsing any HTML white space and allowing you to provide alignment control with [spacing]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) and [flexbox]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/) utilities.
- Controls and input groups receive `width: auto` to override the Bootstrap default `width: 100%`.
- Controls **only appear inline in viewports that are at least 576px wide** to account for narrow viewports on mobile devices.

2017-05-29 20:38:06 +02:00
You may need to manually address the width and alignment of individual form controls with [spacing utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) (as shown below). Lastly, be sure to always include a `<label>` with each form control, even if you need to hide it from non-screenreader visitors with `.sr-only`.

##### Alternatives to hidden labels
2016-05-09 07:52:58 +02:00
Assistive technologies such as screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the `.sr-only` class. There are further alternative methods of providing a label for assistive technologies, such as the `aria-label`, `aria-labelledby` or `title` attribute. If none of these are present, assistive technologies may resort to using the `placeholder` attribute, if present, but note that use of `placeholder` as a replacement for other labelling methods is not advised.

## Help text
2014-07-12 07:34:47 +02:00
2017-06-14 07:11:44 +02:00
Block-level help text in forms can be created using `.form-text` (previously known as `.help-block` in v3). Inline help text can be flexibly implemented using any inline HTML element and utility classes like `.text-muted`.

##### Associating help text with form controls
2014-03-17 03:03:53 +01:00
2017-06-14 07:11:44 +02:00
Help text should be explicitly associated with the form control it relates to using the `aria-describedby` attribute. This will ensure that assistive technologies—such as screen readers—will announce this help text when the user focuses or enters the control.

##### Caveat with anchors
2014-03-17 03:03:53 +01:00
By default, browsers will treat all native form controls (`<input>`, `<select>` and `<button>` elements) inside a `<fieldset disabled>` as disabled, preventing both keyboard and mouse interactions on them. However, if your form also includes `<a ... class="btn btn-*">` elements, these will only be given a style of `pointer-events: none`. As noted in the section about [disabled state for buttons]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/buttons/#disabled-state) (and specifically in the sub-section for anchor elements), this CSS property is not yet standardized and isn't fully supported in Internet Explorer 10, and won't prevent keyboard users from being able to focus or activate these links. So to be safe, use custom JavaScript to disable such links.
{% endcapture %}
{% include callout.html content=callout type="warning" %}
{% capture callout %}
#### Cross-browser compatibility
While Bootstrap will apply these styles in all browsers, Internet Explorer 11 and below don't fully support the `disabled` attribute on a `<fieldset>`. Use custom JavaScript to disable the fieldset in these browsers.
{% endcapture %}
{% include callout.html content=callout type="danger" %}

## Validation
2014-03-17 03:03:53 +01:00
Provide valuable, actionable feedback to your users with HTML5 form validation[available in all our supported browsers](https://caniuse.com/#feat=form-validation). Choose from the browser default validation feedback, or implement custom messages with our built-in classes and starter JavaScript.
2017-06-06 05:21:08 +02:00
{% capture callout %}
We currently recommend using custom validation styles, as native browser default validation messages are not consistently exposed to assistive technologies in all browsers (most notably, Chrome on desktop and mobile).

{% include callout.html content=callout type="warning" %}

### How it works
2017-06-12 01:24:20 +02:00
Here's how form validation works with Bootstrap:
2017-06-06 05:21:08 +02:00
2017-06-12 01:24:20 +02:00
- HTML form validation is applied via CSS's two pseudo-classes, `:invalid` and `:valid`. It applies to `<input>`, `<select>`, and `<textarea>` elements.
- Bootstrap scopes the `:invalid` and `:valid` styles to parent `.was-validated` class, usually applied to the `<form>`. Otherwise, any required field without a value shows up as invalid on page load. This way, you may choose when to activate them (typically after form submission is attempted).
- To reset the appearance of the form (for instance, in the case of dynamic form submissions using AJAX), remove the `.was-validated` class from the `<form>` again after submission.
2017-06-12 01:24:20 +02:00
- As a fallback, `.is-invalid` and `.is-valid` classes may be used instead of the pseudo-classes for [server side validation](#server-side). They do not require a `.was-validated` parent class.
2017-08-06 11:34:10 +02:00
- Due to constraints in how CSS works, we cannot (at present) apply styles to a `<label>` that comes before a form control in the DOM without the help of custom JavaScript.
- All modern browsers support the [constraint validation API](https://www.w3.org/TR/html5/sec-forms.html#the-constraint-validation-api), a series of JavaScript methods for validating form controls.
- Feedback messages may utilize the [browser defaults](#browser-defaults) (different for each browser, and unstylable via CSS) or our custom feedback styles with additional HTML and CSS.
2017-06-06 05:21:08 +02:00
- You may provide custom validity messages with `setCustomValidity` in JavaScript.
2017-06-12 01:24:20 +02:00
With that in mind, consider the following demos for our custom form validation styles, optional server side classes, and browser defaults.
### Custom styles
For custom Bootstrap form validation messages, you'll need to add the `novalidate` boolean attribute to your `<form>`. This disables the browser default feedback tooltips, but still provides access to the form validation APIs in JavaScript. Try to submit the form below; our JavaScript will intercept the submit button and relay feedback to you. When attempting to submit, you'll see the `:invalid` and `:valid` styles applied to your form controls.
Custom feedback styles apply custom colors, borders, focus styles, and background icons to better communicate feedback. Background icons for `<select>`s are only available with `.custom-select`, and not `.form-control`.

### Browser defaults
Not interested in custom validation feedback messages or writing JavaScript to change form behaviors? All good, you can use the browser defaults. Try submitting the form below. Depending on your browser and OS, you'll see a slightly different style of feedback.
While these feedback styles cannot be styled with CSS, you can still customize the feedback text through JavaScript.

### Server side
We recommend using client-side validation, but in case you require server-side validation, you can indicate invalid and valid form fields with `.is-invalid` and `.is-valid`. Note that `.invalid-feedback` is also supported with these classes.

Our example forms show native textual `<input>`s above, but form validation styles are also available for `<textarea>`s and custom form controls.
2018-03-14 16:44:38 +01:00
{% capture example %}
<form class="was-validated">

{% endcapture %}
{% include example.html content=example %}
### Tooltips
If your form layout allows it, you can swap the `.{valid|invalid}-feedback` classes for `.{valid|invalid}-tooltip` classes to display validation feedback in a styled tooltip. Be sure to have a parent with `position: relative` on it for tooltip positioning. In the example below, our column classes have this already, but your project may require an alternative setup.
2018-03-14 16:44:38 +01:00
{% capture example %}
<form class="needs-validation" novalidate>
<div class="form-row">
<div class="col-md-4 mb-3">
<label for="validationTooltip01">First name</label>
<input type="text" class="form-control" id="validationTooltip01" placeholder="First name" value="Mark" required>

## Custom forms
For even more customization and cross browser consistency, use our completely custom form elements to replace the browser defaults. They're built on top of semantic and accessible markup, so they're solid replacements for any default form control.
### Checkboxes and radios
Each checkbox and radio `<input>` and `<label>` pairing is wrapped in a `<div>` to create our custom control. Structurally, this is the same approach as our default `.form-check`.
We use the sibling selector (`~`) for all our `<input>` states—like `:checked`—to properly style our custom form indicator. When combined with the `.custom-control-label` class, we can also style the text for each item based on the `<input>`'s state.
We hide the default `<input>` with `opacity` and use the `.custom-control-label` to build a new custom form indicator in its place with `::before` and `::after`. Unfortunately we can't build a custom one from just the `<input>` because CSS's `content` doesn't work on that element.
In the checked states, we use **base64 embedded SVG icons** from [Open Iconic](https://github.com/iconic/open-iconic). This provides us the best control for styling and positioning across browsers and devices.
#### Checkboxes
2018-03-14 16:44:38 +01:00
{% capture example %}
<div class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" id="customCheck1">
<label class="custom-control-label" for="customCheck1">Check this custom checkbox</label>
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
Custom checkboxes can also utilize the `:indeterminate` pseudo class when manually set via JavaScript (there is no available HTML attribute for specifying it).
<div class="bd-example bd-example-indeterminate">
<div class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" id="customCheck2">
<label class="custom-control-label" for="customCheck2">Check this custom checkbox</label>
</div>
</div>
If you're using jQuery, something like this should suffice:
{% highlight js %}
$('.your-checkbox').prop('indeterminate', true)
{% endhighlight %}
#### Radios
2018-03-14 16:44:38 +01:00
{% capture example %}
<div class="custom-control custom-radio">
<input type="radio" id="customRadio1" name="customRadio" class="custom-control-input">
<label class="custom-control-label" for="customRadio1">Toggle this custom radio</label>
</div>
<div class="custom-control custom-radio">
<input type="radio" id="customRadio2" name="customRadio" class="custom-control-input">
<label class="custom-control-label" for="customRadio2">Or toggle this other custom radio</label>
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
#### Inline
2018-03-14 16:44:38 +01:00
{% capture example %}
<div class="custom-control custom-radio custom-control-inline">
<input type="radio" id="customRadioInline1" name="customRadioInline1" class="custom-control-input">
<label class="custom-control-label" for="customRadioInline1">Toggle this custom radio</label>
</div>
<div class="custom-control custom-radio custom-control-inline">
<input type="radio" id="customRadioInline2" name="customRadioInline1" class="custom-control-input">
<label class="custom-control-label" for="customRadioInline2">Or toggle this other custom radio</label>
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
#### Disabled
Custom checkboxes and radios can also be disabled. Add the `disabled` boolean attribute to the `<input>` and the custom indicator and label description will be automatically styled.
2018-03-14 16:44:38 +01:00
{% capture example %}
<div class="custom-control custom-checkbox">
<input type="checkbox" class="custom-control-input" id="customCheckDisabled1" disabled>
<label class="custom-control-label" for="customCheckDisabled1">Check this custom checkbox</label>
</div>
<div class="custom-control custom-radio">
<input type="radio" name="radioDisabled" id="customRadioDisabled2" class="custom-control-input" disabled>
<label class="custom-control-label" for="customRadioDisabled2">Toggle this custom radio</label>
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
### Switches
A switch has the markup of a custom checkbox but uses the `.custom-switch` class to render a toggle switch. Switches also support the `disabled` attribute.
{% capture example %}
<div class="custom-control custom-switch">
<input type="checkbox" class="custom-control-input" id="customSwitch1">
<label class="custom-control-label" for="customSwitch1">Toggle this switch element</label>
</div>
<div class="custom-control custom-switch">
<input type="checkbox" class="custom-control-input" disabled id="customSwitch2">
<label class="custom-control-label" for="customSwitch2">Disabled switch element</label>
</div>
{% endcapture %}
{% include example.html content=example %}
### Select menu
Custom `<select>` menus need only a custom class, `.custom-select` to trigger the custom styles. Custom styles are limited to the `<select>`'s initial appearance and cannot modify the `<option>`s due to browser limitations.
2018-03-14 16:44:38 +01:00
{% capture example %}
2016-01-06 08:34:51 +01:00
<select class="custom-select">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
You may also choose from small and large custom selects to match our similarly sized text inputs.
2018-03-14 16:44:38 +01:00
{% capture example %}
2017-12-23 06:18:45 +01:00
<select class="custom-select custom-select-lg mb-3">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<select class="custom-select custom-select-sm">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
The `multiple` attribute is also supported:
2018-03-14 16:44:38 +01:00
{% capture example %}
<select class="custom-select" multiple>
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
As is the `size` attribute:
2018-03-14 16:44:38 +01:00
{% capture example %}
<select class="custom-select" size="3">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
### Range
Create custom `<input type="range">` controls with `.custom-range`. The track (the background) and thumb (the value) are both styled to appear the same across browsers. As only IE and Firefox support "filling" their track from the left or right of the thumb as a means to visually indicate progress, we do not currently support it.
2018-03-14 16:44:38 +01:00
{% capture example %}
<label for="customRange1">Example range</label>
<input type="range" class="custom-range" id="customRange1">
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
Range inputs have implicit values for `min` and `max`—`0` and `100`, respectively. You may specify new values for those using the `min` and `max` attributes.
2018-03-14 16:44:38 +01:00
{% capture example %}
<label for="customRange2">Example range</label>
<input type="range" class="custom-range" min="0" max="5" id="customRange2">
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
By default, range inputs "snap" to integer values. To change this, you can specify a `step` value. In the example below, we double the number of steps by using `step="0.5"`.
2018-03-14 16:44:38 +01:00
{% capture example %}
<label for="customRange3">Example range</label>
<input type="range" class="custom-range" min="0" max="5" step="0.5" id="customRange3">
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
### File browser
{% capture callout %}
The recommended plugin to animate custom file input: [bs-custom-file-input](https://www.npmjs.com/package/bs-custom-file-input), that's what we are using currently here in our docs.
{% endcapture %}
{% include callout.html content=callout type="info" %}
The file input is the most gnarly of the bunch and requires additional JavaScript if you'd like to hook them up with functional *Choose file...* and selected file name text.
2018-03-14 16:44:38 +01:00
{% capture example %}
<div class="custom-file">
<input type="file" class="custom-file-input" id="customFile">
<label class="custom-file-label" for="customFile">Choose file</label>
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
We hide the default file `<input>` via `opacity` and instead style the `<label>`. The button is generated and positioned with `::after`. Lastly, we declare a `width` and `height` on the `<input>` for proper spacing for surrounding content.
#### Translating or customizing the strings with SCSS
The [`:lang()` pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:lang) is used to allow for translation of the "Browse" text into other languages. Override or add entries to the `$custom-file-text` Sass variable with the relevant [language tag](https://en.wikipedia.org/wiki/IETF_language_tag) and localized strings. The English strings can be customized the same way. For example, here's how one might add a Spanish translation (Spanish's language code is `es`):
{% highlight scss %}
$custom-file-text: (
en: "Browse",
es: "Elegir"
);
{% endhighlight %}
Here's `lang(es)` in action on the custom file input for a Spanish translation:
2018-03-14 16:44:38 +01:00
{% capture example %}
<div class="custom-file">
<input type="file" class="custom-file-input" id="customFileLang" lang="es">
<label class="custom-file-label" for="customFileLang">Seleccionar Archivo</label>
</div>
2018-03-14 16:44:38 +01:00
{% endcapture %}
{% include example.html content=example %}
You'll need to set the language of your document (or subtree thereof) correctly in order for the correct text to be shown. This can be done using [the `lang` attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/lang) on the `<html>` element or the [`Content-Language` HTTP header](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.12), among other methods.
#### Translating or customizing the strings with HTML
Bootstrap also provides a way to translate the "Browse" text in HTML with the `data-browse` attribute which can be added to the custom input label (example in Dutch):
{% capture example %}
<div class="custom-file">
<input type="file" class="custom-file-input" id="customFileLangHTML">
<label class="custom-file-label" for="customFileLangHTML" data-browse="Bestand kiezen">Voeg je document toe</label>
</div>
{% endcapture %}
{% include example.html content=example %}
