Input Groups
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.
Cross-browser compatibility
Avoid using <select> elements here as they cannot be fully styled in WebKit browsers.
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.
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.
<div class="input-group">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
<div class="input-group">
<input type="text" class="form-control">
<span class="input-group-addon">.00</span>
</div>
<div class="input-group">
<span class="input-group-addon">$</span>
<input type="text" class="form-control">
<span class="input-group-addon">.00</span>
</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-lg">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
<div class="input-group">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
<div class="input-group input-group-sm">
<span class="input-group-addon">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>
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.
<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">
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
<div class="col-lg-6">
<div class="input-group">
<input type="text" class="form-control">
<span class="input-group-btn">
<button class="btn btn-default" type="button">Go!</button>
</span>
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
</div><!-- /.row -->
