Input Group

Easily extend form controls by adding text, buttons, or button groups on either side of textual <input>s.

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.

<div class="input-group">
  <span class="input-group-addon" id="basic-addon1">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>
<br>
<div class="input-group">
  <input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
  <span class="input-group-addon" id="basic-addon2">@example.com</span>
</div>
<br>
<label for="basic-url">Your vanity URL</label>
<div class="input-group">
  <span class="input-group-addon" id="basic-addon3">https://example.com/users/</span>
  <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>
<br>
<div class="input-group">
  <span class="input-group-addon">$</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  <span class="input-group-addon">.00</span>
</div>
<br>
<div class="input-group">
  <span class="input-group-addon">$</span>
  <span class="input-group-addon">0.00</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
</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.

<div class="input-group input-group-xl">
  <span class="input-group-addon" id="sizing-addon0">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="sizing-addon0">
</div>
<br>
<div class="input-group input-group-lg">
  <span class="input-group-addon" id="sizing-addon1">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="sizing-addon1">
</div>
<br>
<div class="input-group input-group">
  <span class="input-group-addon" id="sizing-addon2">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="sizing-addon2">
</div>
<br>
<div class="input-group input-group-sm">
  <span class="input-group-addon" id="sizing-addon3">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="sizing-addon3">
</div>
<br>
<div class="input-group input-group-xs">
  <span class="input-group-addon" id="sizing-addon4">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="sizing-addon4">
</div>

Checkboxes and Radio Addons

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

<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="checkbox" aria-label="Checkbox for following text input">
      </span>
      <input type="text" class="form-control" aria-label="Text input with checkbox">
    </div>
  </div>
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="radio" aria-label="Radio button for following text input">
      </span>
      <input type="text" class="form-control" aria-label="Text input with radio button">
    </div>
  </div>
</div>

Multiple Addons

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

<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="checkbox" aria-label="Checkbox for following text input">
      </span>
      <span class="input-group-addon">$</span>
      <input type="text" class="form-control" aria-label="Text input with checkbox">
    </div>
  </div>
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">$</span>
      <span class="input-group-addon">0.00</span>
      <input type="text" class="form-control" aria-label="Text input with radio button">
    </div>
  </div>
</div>

Button Addons

Buttons in input groups must wrapped in a .input-group-btn for proper alignment and sizing. This is required due to default browser styles that cannot be overridden.

<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-btn">
        <button class="btn" type="button">Go!</button>
      </span>
      <input type="text" class="form-control" placeholder="Search for...">
    </div>
  </div>
  <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" type="button">Go!</button>
      </span>
    </div>
  </div>
</div>
<br>
<div class="row">
  <div class="col-lg-offset-3 col-lg-6">
    <div class="input-group">
      <span class="input-group-btn">
        <button class="btn" type="button">Hate it</button>
      </span>
      <input type="text" class="form-control" placeholder="Product name">
      <span class="input-group-btn">
        <button class="btn" type="button">Love it</button>
      </span>
    </div>
  </div>
</div>

Buttons with Dropdowns

<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <div class="input-group-btn">
        <button type="button" class="btn dropdown-toggle" data-cfw="dropdown">

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.

There is also an issue when placing buttons before inputs, as this can cause a confusing ordering issue for those using screen readers, where the general expectation is that the buttons are at the end of a form, or at least, after the inputs. This fix is not as simple as controlling the focus order since screen readers read in order of the DOM elements. There might be ways to mitigate this using a description of some kind, but it might be better to ensure proper ordering of the elements, and putting the buttons after any input elements.
