docs Input group Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs. components true

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.

{% example html %}

@
@example.com

$
.00
{% endexample %}

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.

Checkboxes and radios

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

{% example html %}

{% endexample %}

Multiple inputs

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

{% example html %}

First and last name

Multiple addons

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

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.
