How to make nested vertical menu with jQuery accordion?

Can anyone point me to a good example on how to implement nested vertical menu using jQuery accordion? Something like here (at the left of the page, starting from third item), but nested. There is no example of nested structure in Accordion docs on some reason.

Or may be there is开发者_如何转开发 a good jQuery component on organizing vertical nested menus I somehow missed (whatever based, not necessarily accordion)? I beleive there should be one. Can you suggest some with good initial design and preferably easily skinnable?

i made one by myself a time ago, you could use it : the example in the web itself : http://www.corbins.cat/ the plugin source : http://www.corbins.cat/lib/js/accordion.js

edit : i updated my plugin a little bit

give it a try, is nested yes, you should make html like that

<ul>
  <li><h4 class="trigger">title one</h4>
   <ul>
      <li><h4> class="trigger">title one.one</h4>
         <ul>
            <li> item one.one.one</li>
            <li> item one.one.two</li>
            <li> item one.one.three</li>
         </ul>
     <li>item one.two</li>
   </ul>
 <li>item two</li>
</ul>

let me know how it works for you! :)
