Basic example

Place one add-on or button on either side of an input. You may also place one on both sides of an input. We do not support multiple form-controls in a single input group and <label>s must come outside the input group.

{% capture example %}

@

@example.com

Your vanity URL

https://example.com/users/

$

.00

With textarea

{% endcapture %} {% include example.html content=example %}

Sizing

Add the relative form sizing classes to the .input-group itself and contents within will automatically resize—no need for repeating the form control size classes on each element.

Sizing on the individual input group elements isn't supported.

{% capture example %}

Small

Default

Large

{% endcapture %} {% include example.html content=example %}

Checkboxes and radios

Place any checkbox or radio option within an input group's addon instead of text.

{% capture example %}

{% endcapture %} {% include example.html content=example %}

Multiple inputs

While multiple <input>s are supported visually, validation styles are only available for input groups with a single <input>.

{% capture example %}

First and last name

{% endcapture %} {% include example.html content=example %}

Multiple addons

Multiple add-ons are supported and can be mixed with checkbox and radio input versions.

$ 0.00

Accessibility

Screen readers will have trouble with your forms if you don't include a label for every input. For these input groups, ensure that any additional label or functionality is conveyed to assistive technologies.

The exact technique to be used (<label> elements hidden using the .sr-only class, or use of the aria-label and aria-labelledby attributes, possibly in combination with aria-describedby) and what additional information will need to be conveyed will vary depending on the exact type of interface widget you're implementing. The examples in this section provide a few suggested, case-specific approaches.
