Basic Collapsible
Collapsibles are useful when you want to hide and show large amount of content:

Click Me
Example
<button data-toggle="collapse" data-target="#demo">Collapsible</button>

<div id="demo" class="collapse">
Lorem ipsum dolor text....
</div>
»
Example Explained
The .collapse class indicates a collapsible element (a <div> in our example); this is the content that will be shown or hidden with a click of a button.

To control (show/hide) the collapsible content, add the data-toggle="collapse" attribute to an <a> or a <button> element. Then add the data-target="#id" attribute to connect the button with the collapsible content (<div id="demo">).

Note: For <a> elements, you can use the href attribute instead of the data-target attribute:

Example
<a href="#demo" data-toggle="collapse">Collapsible</a>

<div id="demo" class="collapse">
Lorem ipsum dolor text....
</div>
»
By default, the collapsible content is hidden. However, you can add the .in class to show the content by default:

Example
<div id="demo" class="collapse in">
Lorem ipsum dolor text....
</div>
»

    <div class="panel-heading">
      <h4 class="panel-title">

      sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad
      minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea
