<div class="bs-docs-section">
  <h1 id="input-groups" class="page-header">Input groups</h1>

  <p class="lead">Extend form controls by adding text or buttons before, after, or on both sides of any text-based <code>&lt;input&gt;</code>. Use <code>.input-group</code> with an <code>.input-group-addon</code> to prepend or append elements to a single <code>.form-control</code>.</p>

  <div class="bs-callout bs-callout-danger" id="callout-inputgroup-text-input-only">
    <h4>Textual <code>&lt;input&gt;</code>s only</h4>
    <p>Avoid using <code>&lt;select&gt;</code> elements here as they cannot be fully styled in WebKit browsers.</p>
    <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" id="callout-inputgroup-container-body">
    <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" id="callout-inputgroup-dont-mix">
    <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>


  <h2 id="input-groups-basic">Basic example</h2>
  <p>Place one add-on or button on either side of an input. You may also place one on both sides of an input.</p>
  <p><strong class="text-danger">We do not support multiple add-ons on a single side.</strong></p>
  <p><strong class="text-danger">We do not support multiple form-controls in a single input group.</strong></p>

  <p>Add the relative form sizing classes to the <code>.input-group</code> itself and contents within will automatically resize—no need for repeating the form control size classes on each element.</p>

  <h2 id="input-groups-buttons">Button addons</h2>
  <p>Buttons in input groups are a bit different and require one extra level of nesting. Instead of <code>.input-group-addon</code>, you'll need to use <code>.input-group-btn</code> to wrap the buttons. This is required due to default browser styles that cannot be overridden.</p>
