+
+### Using data attributes
+
+You can activate a list group navigation without writing any JavaScript by simply specifying `data-toggle="list"` or  on an element. Use these data attributes on `.list-group-item`.
+
+<div role="tabpanel">
+{% highlight html %}
+<!-- List group -->
+<div class="list-group" id="myList" role="tablist">
+  <a class="list-group-item list-group-item-action active" data-toggle="list" href="#home" role="tab">Home</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#profile" role="tab">Profile</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#messages" role="tab">Messages</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#settings" role="tab">Settings</a>
+</div>
+
+<!-- Tab panes -->
+<div class="tab-content">
+  <div class="tab-pane active" id="home" role="tabpanel">...</div>
+  <div class="tab-pane" id="profile" role="tabpanel">...</div>
+  <div class="tab-pane" id="messages" role="tabpanel">...</div>
+  <div class="tab-pane" id="settings" role="tabpanel">...</div>
+</div>
+{% endhighlight %}
+</div>
+
+### Via JavaScript
+
+Enable tabbable list item via JavaScript (each list item needs to be activated individually):
+
+{% highlight js %}
+$('#myList a').click(function (e) {
+  e.preventDefault()
+  $(this).tab('show')
+})
+{% endhighlight %}
+
+You can activate individual list item in several ways:
+
+{% highlight js %}
+$('#myList a[href="#profile"]').tab('show') // Select tab by name
+$('#myList a:first').tab('show') // Select first tab
+$('#myList a:last').tab('show') // Select last tab
+$('#myList li:eq(2) a').tab('show') // Select third tab (0-indexed)
+{% endhighlight %}
+
+### Fade effect
+
+To make tabs panel fade in, add `.fade` to each `.tab-pane`. The first tab pane must also have `.show` to make the initial content visible.
+
+{% highlight html %}
+<div class="tab-content">
+  <div class="tab-pane fade show active" id="home" role="tabpanel">...</div>
+  <div class="tab-pane fade" id="profile" role="tabpanel">...</div>
+  <div class="tab-pane fade" id="messages" role="tabpanel">...</div>
+  <div class="tab-pane fade" id="settings" role="tabpanel">...</div>
+</div>
+{% endhighlight %}
+
+### Methods
+
+#### $().tab
+
+Activates a list item element and content container. Tab should have either a `data-target` or an `href` targeting a container node in the DOM.
+
+{% highlight html %}
+<div class="list-group" id="myList" role="tablist">
+  <a class="list-group-item list-group-item-action active" data-toggle="list" href="#home" role="tab">Home</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#profile" role="tab">Profile</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#messages" role="tab">Messages</a>
+  <a class="list-group-item list-group-item-action" data-toggle="list" href="#settings" role="tab">Settings</a>
+</div>
+
+<div class="tab-content">
+  <div class="tab-pane active" id="home" role="tabpanel">...</div>
+  <div class="tab-pane" id="profile" role="tabpanel">...</div>
+  <div class="tab-pane" id="messages" role="tabpanel">...</div>
+  <div class="tab-pane" id="settings" role="tabpanel">...</div>
+</div>
+
+<script>
+  $(function () {
+    $('#myList a:last').tab('show')
+  })
+</script>
+{% endhighlight %}
+
+#### .tab('show')
+
+Selects the given list item and shows its associated pane. Any other list item that was previously selected becomes unselected and its associated pane is hidden. **Returns to the caller before the tab pane has actually been shown** (for example, before the `shown.bs.tab` event occurs).
+
+{% highlight js %}
+$('#someListItem').tab('show')
+{% endhighlight %}
+
+### Events
+
+When showing a new tab, the events fire in the following order:
+
+1. `hide.bs.tab` (on the current active tab)
+2. `show.bs.tab` (on the to-be-shown tab)
+3. `hidden.bs.tab` (on the previous active tab, the same one as for the `hide.bs.tab` event)
+4. `shown.bs.tab` (on the newly-active just-shown tab, the same one as for the `show.bs.tab` event)
+
+If no tab was already active, the `hide.bs.tab` and `hidden.bs.tab` events will not be fired.
+
+<table class="table table-bordered table-striped table-responsive">

+   <tr>

+    <tr>
+      <td>show.bs.tab</td>
+      <td>This event fires on tab show, but before the new tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
+   </tr>
+   <tr>
+      <td>shown.bs.tab</td>
+      <td>This event fires on tab show after a tab has been shown. Use <code>event.target</code> and <code>event.relatedTarget</code> to target the active tab and the previous active tab (if available) respectively.</td>
+    </tr>
+    <tr>
+      <td>hide.bs.tab</td>
+      <td>This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use <code>event.target</code> and <code>event.relatedTarget</code> to target the current active tab and the new soon-to-be-active tab, respectively.</td>

+    <tr>
+      <td>hidden.bs.tab</td>
