jquery sidebar menu

I'm looking for a jQuery plugin sidebar menu with horizontal collapse/expand and hopefully drag-n-drop resize. It would nice if it take the following list for menu options:

<ul>
  <li><a href="#">option 1</a></li>
  <ul>
      <li><a href="#">sub-option A</a></li>
  </ul>
  <li>开发者_开发百科<a href="#">option 2</a></li>
  <li><a href="#">option 3</a></li>
</ul>

Does anyone have recommendations or suggestions?

I like the approach of jQuerySideBar Plugin but would prefer something a little simpler and more flexible.

It sounds like you're talking about an Accordion.

You should also check out jQuery UI's Resizable feature.

There is a horizontal accordion here:
