Minimize

Textual <input>s only

Avoid using <select> elements here as they cannot be fully styled in WebKit browsers.

Avoid using <textarea> elements here as their rows attribute will not be respected in some cases.

Tooltips & popovers in input groups require special setting

When using tooltips or popovers on elements within an .input-group, you'll have to specify the option container: 'body' to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).

Don't mix with other components

Do not mix form groups or grid column classes directly with input groups. Instead, nest the input group inside of the form group or grid-related element.

Always add labels

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 (visible <label> elements, <label> elements hidden using the .sr-only class, or use of the aria-label, aria-labelledby, aria-describedby, title or placeholder attribute) 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.

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 add-ons (.input-group-addon or .input-group-btn) on a single side.

We do not support multiple form-controls in a single input group.

  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  <span class="input-group-addon">.00</span>
</div>

<label for="basic-url">Your vanity URL</label>
<div class="input-group">

  <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>

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.

  <span class="input-group-addon" id="sizing-addon3">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon3">
</div>

Checkboxes and radio addons

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

Copy
<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="checkbox" aria-label="...">
      </span>
      <input type="text" class="form-control" aria-label="...">
    </div><!-- /input-group -->
  </div><!-- /.col-lg-6 -->
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="radio" aria-label="...">
      </span>
      <input type="text" class="form-control" aria-label="...">
    </div><!-- /input-group -->
  </div><!-- /.col-lg-6 -->
</div><!-- /.row -->

Button addons

Buttons in input groups are a bit different and require one extra level of nesting. Instead of .input-group-addon, you'll need to use .input-group-btn to wrap the buttons. This is required due to default browser styles that cannot be overridden.

Copy
<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-btn">
        <button class="btn btn-default" type="button">Go!</button>
      </span>
      <input type="text" class="form-control" placeholder="Search for...">
    </div><!-- /input-group -->
  </div><!-- /.col-lg-6 -->
  <div class="col-lg-6">
    <div class="input-group">
      <input type="text" class="form-control" placeholder="Search for...">
      <span class="input-group-btn">
        <button class="btn btn-default" type="button">Go!</button>
      </span>
    </div><!-- /input-group -->
  </div><!-- /.col-lg-6 -->
</div><!-- /.row -->

Buttons with dropdowns

Copy
<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <div class="input-group-btn">
        <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Action <span class="caret"></span></button>
        <ul class="dropdown-menu">
          <li><a href="#">Action</a></li>
          <li><a href="#">Another action</a></li>
          <li><a href="#">Something else here</a></li>
          <li role="separator" class="divider"></li>
          <li><a href="#">Separated link</a></li>
        </ul>
      </div><!-- /btn-group -->
      <input type="text" class="form-control" aria-label="...">
    </div><!-- /input-group -->
  </div><!-- /.col-lg-6 -->
  <div class="col-lg-6">
    <div class="input-group">
      <input type="text" class="form-control" aria-label="...">
      <div class="input-group-btn">
        <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Action <span class="caret"></span></button>
        <ul class="dropdown-menu dropdown-menu-right">
          <li><a href="#">Action</a></li>
          <li><a href="#">Another action</a></li>
          <li><a href="#">Something else here</a></li>
          <li role="separator" class="divider"></li>
          <li><a href="#">Separated link</a></li>
        </ul>
      </div><!-- /btn-group -->
    </div><!-- /input-group -->
  </div><!-- /.col-lg-6 -->
</div><!-- /.row -->

Segmented buttons

Copy
<div class="input-group">
  <div class="input-group-btn">
    <!-- Button and dropdown menu -->
  </div>
  <input type="text" class="form-control" aria-label="...">
</div>

<div class="input-group">
  <input type="text" class="form-control" aria-label="...">
  <div class="input-group-btn">
    <!-- Button and dropdown menu -->
  </div>
</div>

Multiple buttons

While you can only have one add-on per side, you can have multiple buttons inside a single .input-group-btn.

Copy
<div class="input-group">
  <div class="input-group-btn">
    <!-- Buttons -->
  </div>
  <input type="text" class="form-control" aria-label="...">
</div>

<div class="input-group">
  <input type="text" class="form-control" aria-label="...">
  <div class="input-group-btn">
    <!-- Buttons -->
  </div>
</div>
