<h3>About</h3>
<p>Get base styles and flexible support for collapsible components like accordions and navigation.</p>

<p>Collapse requires the <a href="#transitions">transitions plugin</a> to be included in your version of Bootstrap.</p>

<p>Using the collapse plugin, we built a simple accordion by extending the panel component.</p>

<p>You can also use the plugin without the accordion markup. Make a button toggle the expanding and collapsing of another element.</p>
{% highlight html %}
<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">
simple collapsible
</button>
<div id="demo" class="collapse in">...</div>
{% endhighlight %}
<h2 id="collapse-usage">Usage</h2>
<p>The collapse plugin utilizes a few classes to handle the heavy lifting:</p>
<ul>
<li><code>.collapse</code> hides the content</li>
<li><code>.collapse.in</code> shows the content</li>
<li><code>.collapsing</code> is added when the transition starts, and removed when it finishes</li>
</ul>
<p>These classes can be found in <code>component-animations.less</code>.</p>
<h3>Via data attributes</h3>
<p>Just add <code>data-toggle="collapse"</code> and a <code>data-target</code> to element to automatically assign control of a collapsible element. The <code>data-target</code> attribute accepts a CSS selector to apply the collapse to. Be sure to add the class <code>collapse</code> to the collapsible element. If you'd like it to default open, add the additional class <code>in</code>.</p>
<p>To add accordion-like group management to a collapsible control, add the data attribute <code>data-parent="#selector"</code>. Refer to the demo to see this in action.</p>
<h3>Via JavaScript</h3>
<p>Enable manually with:</p>
{% highlight js %}
$('.collapse').collapse()
{% endhighlight %}
<h3>Options</h3>
<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-parent=""</code>.</p>
<div class="table-responsive">
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 100px;">Name</th>
<th style="width: 50px;">type</th>
<th style="width: 50px;">default</th>
<th>description</th>
</tr>
</thead>
<tbody>
<tr>
<td>parent</td>
<td>selector</td>
<td>false</td>
<td>If selector then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this dependent on the <code>panel</code> class)</td>
</tr>
<tr>
<td>toggle</td>
<td>boolean</td>
<td>true</td>
<td>Toggles the collapsible element on invocation</td>
</tr>
</tbody>
</table>
</div><!-- /.table-responsive -->
<h3>Methods</h3>
<h4>.collapse(options)</h4>
<p>Activates your content as a collapsible element. Accepts an optional options <code>object</code>.
{% highlight js %}
$('#myCollapsible').collapse({
toggle: false
})
{% endhighlight %}
<h4>.collapse('toggle')</h4>
<p>Toggles a collapsible element to shown or hidden.</p>
<h4>.collapse('show')</h4>
<p>Shows a collapsible element.</p>
<h4>.collapse('hide')</h4>
<p>Hides a collapsible element.</p>
<h3>Events</h3>
<p>Bootstrap's collapse class exposes a few events for hooking into collapse functionality.</p>
<div class="table-responsive">
<table class="table table-bordered table-striped">
<thead>
<tr>
<th style="width: 150px;">Event Type</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>show.bs.collapse</td>
<td>This event fires immediately when the <code>show</code> instance method is called.</td>
</tr>
<tr>
<td>shown.bs.collapse</td>
<td>This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete).</td>
</tr>
<tr>
<td>hide.bs.collapse</td>
<td>
This event is fired immediately when the <code>hide</code> method has been called.
</td>
</tr>
<tr>
<td>hidden.bs.collapse</td>
<td>This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete).</td>
</tr>
</tbody>
</table>
</div><!-- /.table-responsive -->
{% highlight js %}
$('#myCollapsible').on('hidden.bs.collapse', function () {
// do something…
})
{% endhighlight %}
</div>
