[jQuery] treeview - way to ignore a list from treeview

I am displaying some lists, and some of the list li's display user
generated content. Some of that conetnt seems to have lists in them.
Is there a way to specifically say that treeview should only process
certain uls or lis and ignore others?

e.g.

<ul class="filetree">
<li>
<!-- begin user content -->
<ul>
<li>my user list</li>
<li>my user list</li>
</ul>
<p>a paragraph</p>
<!-- end user content -->
</li>
</ul>

I'd like treeview to ignore the ul in the user content.

TIA
