title: How to make a Bootstrap accordion collapse when clicking the header div?
body: <p>In a Bootstrap accordion, instead of requiring a click on the <code>a</code> text, I want to make it collapse when clicking anywhere in the <code>panel-heading</code> div.</p>
  
  <p>I am using Bootstrap 3. So instead of accordion, it's just a collapsible panel. Any idea how to do the entire panel clickable?</p>
