    <h4>Extends tabbed navigation</h4>
    <p>This plugin extends the <a href="../components/#nav-tabs">tabbed navigation component</a> to add tabbable areas.</p>
  </div>


  <h2 id="tabs-usage">Usage</h2>
  <p>Enable tabbable tabs via JavaScript (each tab needs to be activated individually):</p>

{% highlight js %}
$('#myTab a').click(function (e) {
  e.preventDefault()
  $(this).tab('show')
})
{% endhighlight %}

  <p>You can activate individual tabs in several ways:</p>

{% highlight js %}
$('#myTab a[href="#profile"]').tab('show') // Select tab by name
$('#myTab a:first').tab('show') // Select first tab
$('#myTab a:last').tab('show') // Select last tab
$('#myTab li:eq(2) a').tab('show') // Select third tab (0-indexed)
{% endhighlight %}

  <h3>Markup</h3>
  <p>You can activate a tab or pill navigation without writing any JavaScript by simply specifying <code>data-toggle="tab"</code> or <code>data-toggle="pill"</code> on an element. Adding the <code>nav</code> and <code>nav-tabs</code> classes to the tab <code>ul</code> will apply the Bootstrap <a href="../components/#nav-tabs">tab styling</a>, while adding the <code>nav</code> and <code>nav-pills</code> classes will apply <a href="../components/#nav-pills">pill styling</a>.</p>
{% highlight html %}
<!-- Nav tabs -->
<ul class="nav nav-tabs" role="tablist">
  <li role="presentation" class="active"><a href="#home" role="tab" data-toggle="tab">Home</a></li>
  <li role="presentation"><a href="#profile" role="tab" data-toggle="tab">Profile</a></li>
  <li role="presentation"><a href="#messages" role="tab" data-toggle="tab">Messages</a></li>
  <li role="presentation"><a href="#settings" role="tab" data-toggle="tab">Settings</a></li>
</ul>

<!-- Tab panes -->
<div class="tab-content">
  <div role="tabpanel" class="tab-pane active" id="home">...</div>
  <div role="tabpanel" class="tab-pane" id="profile">...</div>
  <div role="tabpanel" class="tab-pane" id="messages">...</div>
  <div role="tabpanel" class="tab-pane" id="settings">...</div>
</div>
{% endhighlight %}

  <h3>Fade effect</h3>
  <p>To make tabs fade in, add <code>.fade</code> to each <code>.tab-pane</code>. The first tab pane must also have <code>.in</code> to properly fade in initial content.</p>
{% highlight html %}
<div class="tab-content">
  <div role="tabpanel" class="tab-pane fade in active" id="home">...</div>
  <div role="tabpanel" class="tab-pane fade" id="profile">...</div>
  <div role="tabpanel" class="tab-pane fade" id="messages">...</div>
  <div role="tabpanel" class="tab-pane fade" id="settings">...</div>
</div>
{% endhighlight %}

  <h3>Methods</h3>
  <h4>$().tab</h4>
  <p>
    Activates a tab element and content container. Tab should have either a <code>data-target</code> or an <code>href</code> targeting a container node in the DOM.
  </p>
