Bootstrap input group

Bootstrap Input Group allows you to extend and group Bootstrap forms. Learn how to easily extend form controls by adding text, buttons, or button groups.

Basic example

Put one add-on or button on both side of an input. You can place one on both sides of an input.

@
@example.com
https://example.com/users/
$
.00
With textarea
<div class="c-input-group c-mb-3">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text" id="basic-addon1">@</span>
  </div>
  <input type="text" class="c-form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>

<div class="c-input-group c-mb-3">
  <input type="text" class="c-form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
  <div class="c-input-group-append">
    <span class="c-input-group-text" id="basic-addon2">@example.com</span>
  </div>
</div>

<label for="basic-url">Your vanity URL</label>
<div class="c-input-group c-mb-3">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text" id="basic-addon3">https://example.com/users/</span>
  </div>
  <input type="text" class="c-form-control" id="basic-url" aria-describedby="basic-addon3">
</div>

<div class="c-input-group c-mb-3">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text">$</span>
  </div>
  <input type="text" class="c-form-control" aria-label="Amount (to the nearest dollar)">
  <div class="c-input-group-append">
    <span class="c-input-group-text">.00</span>
  </div>
</div>

<div class="c-input-group">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text">With textarea</span>
  </div>
  <textarea class="c-form-control" aria-label="With textarea"></textarea>
</div>

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 .c-flex-nowrap.

@
<div class="c-input-group c-flex-nowrap">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text" id="addon-wrapping">@</span>
  </div>
  <input type="text" class="c-form-control" placeholder="Username" aria-label="Username" aria-describedby="addon-wrapping">
</div>

Sizing

You can append the relative form sizing classes to the .c-input-group itself and contents within will automatically resize.

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

Small
Default
Large
<div class="c-input-group c-input-group-sm c-mb-3">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text" id="inputGroup-sizing-sm">Small</span>
  </div>
  <input type="text" class="c-form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-sm">
</div>

<div class="c-input-group c-mb-3">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text" id="inputGroup-sizing-default">Default</span>
  </div>
  <input type="text" class="c-form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
</div>

<div class="c-input-group c-input-group-lg">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text" id="inputGroup-sizing-lg">Large</span>
  </div>
  <input type="text" class="c-form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
</div>

Checkboxes and radios

Put a checkbox or radio option within an input group’s addon instead of text.

<div class="c-input-group c-mb-3">
  <div class="c-input-group-prepend">
    <div class="c-input-group-text">
      <input type="checkbox" aria-label="Checkbox for following text input">
    </div>
  </div>
  <input type="text" class="c-form-control" aria-label="Text input with checkbox">
</div>

<div class="c-input-group">
  <div class="c-input-group-prepend">
    <div class="c-input-group-text">
      <input type="radio" aria-label="Radio button for following text input">
    </div>
  </div>
  <input type="text" class="c-form-control" aria-label="Text input with radio button">
</div>

Multiple inputs

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

First and last name
<div class="c-input-group">
  <div class="c-input-group-prepend">
    <span class="c-input-group-text">First and last name</span>
  </div>
  <input type="text" aria-label="First name" class="c-form-control">
  <input type="text" aria-label="Last name" class="c-form-control">
</div>

Multiple addons

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

Accessibility

Screen readers will have problems with your forms if you don’t add a label for each input. For those input groups, ensure that any extra label or functionality is communicated to assistive technologies.

The correct 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 data will need to be communicated will vary depending on the specific type of interface widget you’re performing.
