layout: page
title: Input group
---
Extend form controls by adding text or buttons before, after, or on both sides of any text-based `<input>`. Use `.input-group` with an `.input-group-addon` to prepend or append elements to a single `.form-control`.
<div class="bs-callout bs-callout-danger">
<h4>Textual <code>&lt;input&gt;</code>s only</h4>
<p>Avoid using <code>&lt;textarea&gt;</code> elements here as their <code>rows</code> attribute will not be respected in some cases.</p>
</div>
<div class="bs-callout bs-callout-warning">
<h4>Tooltips &amp; popovers in input groups require special setting</h4>
<p>When using tooltips or popovers on elements within an <code>.input-group</code>, you'll have to specify the option <code>container: 'body'</code> to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).</p>
</div>
<div class="bs-callout bs-callout-warning">
<h4>Don't mix with other components</h4>
<p>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.</p>
</div>
## 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 on a single side.**
**We do not support multiple form-controls in a single input group.**
{% example html %}
<div class="input-group">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
<br>
<div class="input-group">
<input type="text" class="form-control">
<span class="input-group-addon">.00</span>
</div>
<br>
<div class="input-group">
<span class="input-group-addon">$</span>
<input type="text" class="form-control">
<span class="input-group-addon">.00</span>
</div>
{% 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.
{% example html %}
<div class="input-group input-group-lg">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
<br>
<div class="input-group">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
<br>
<div class="input-group input-group-sm">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
{% endexample %}
## Checkboxes and radio addons
Place any checkbox or radio option within an input group's addon instead of text.
{% example html %}
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-addon">
<input type="checkbox">
</span>
<input type="text" class="form-control">
</div>
</div>
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-addon">
<input type="radio">
</span>
<input type="text" class="form-control">
</div>
</div>
</div>
{% endexample %}
## 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.
{% example html %}
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-btn">
<button class="btn btn-secondary" type="button">Go!</button>
</span>
<input type="text" class="form-control">
</div>
</div>
<div class="col-lg-6">
<div class="input-group">
<input type="text" class="form-control">
<span class="input-group-btn">
<button class="btn btn-secondary" type="button">Go!</button>
</span>
</div>
</div>
</div>
{% endexample %}
## Buttons with dropdowns
{% example html %}
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<div class="input-group-btn">
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Action</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
<input type="text" class="form-control">
</div>
</div>
<div class="col-lg-6">
<div class="input-group">
<input type="text" class="form-control">
<div class="input-group-btn">
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Action</button>
<ul class="dropdown-menu dropdown-menu-right" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
</div>
</div>
</div>
{% endexample %}
## Segmented buttons
{% example html %}
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<div class="input-group-btn">
<button type="button" class="btn btn-secondary" tabindex="-1">Action</button>
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" tabindex="-1" aria-expanded="false">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
<input type="text" class="form-control">
</div>
</div>
<div class="col-lg-6">
<div class="input-group">
<input type="text" class="form-control">
