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. Remember to place <label>s outside the input group.

{{< example >}}

@

@example.com

Your vanity URL

https://example.com/users/

$

.00

With textarea

{{< /example >}}

Wrapping

Input groups wrap by default via flex-wrap: wrap in order to accommodate custom form field validation within an input group. You may disable this with .flex-nowrap.

{{< example >}}

@

{{< /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.

Checkboxes and radios

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

{{< example >}}

{{< /example >}}

Multiple inputs

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

{{< example >}}

First and last name

{{< /example >}}

Multiple addons

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

Accessibility

Ensure that all form controls have an appropriate accessible name so that their purpose can be conveyed to users of assistive technologies. The simplest way to achieve this is to use a <label> element, or—in the case of buttons—to include sufficiently descriptive text as part of the <button>...</button> content.

For situations where it's not possible to include a visible <label> or appropriate text content, there are alternative ways of still providing an accessible name, such as:

• <label> elements hidden using the .sr-only class
• Pointing to an existing element that can act as a label using aria-labelledby
• Providing a title attribute
• Explicitly setting the accessible name on an element using aria-label

If none of these are present, assistive technologies may resort to using the placeholder attribute as a fallback for the accessible name on <input> and <textarea> elements. The examples in this section provide a few suggested, case-specific approaches.

While using visually hidden content (.sr-only, aria-label, and even placeholder content, which disappears once a form field has content) will benefit assistive technology users, a lack of visible label text may still be problematic for certain users. Some form of visible label is generally the best approach, both for accessibility and usability.
