[jQuery] Partial Accordion Possible?

[jQuery] Partial Accordion Possible?


I've been looking at Jörn's Accordion plugin (http://bassistance.de/
jquery-plugins/jquery-plugin-accordion/) but not found any way to do a
partial accordion (i.e. only apply it to part of a list). I have the
structure:
<ul id="menu">
<li><a href="/">Home</a></li>
<li><strong>Header 1</strong><ul>
<li>Sub 1.1</li>
<li>Sub 1.2</li>
<li>Sub 1.3</li>
</ul></li>
<li>No sub items here</li>
<li>Or here</li>
<li><strong>Header 2</strong><ul>
<li>Sub 2.1</li>
<li>Sub 2.2</li>
<li>Sub 2.3</li>
</ul></li>
</ul>
Only Header 1 and Header 2 should be collapsed.
When I try on this structure, the browser (Firefox 2) freezes when I
click a Header 1 or Header 2.
