O it's working as its being told to do on that page....

You need to include another list inside of your <li>

This should make a collapisble thing

PHP Code:

<ul>
  <li>Parent
    <ul><li>Child</li><li><Child 2</li></ul>
  </li>
<li>Parent 2
    <ul><li>Child</li><li><Child 2</li></ul>
</li>
</ul> 


You have to include Sublists to expand on, does that make sense?
