[jQuery] [treeview] Can I apply classes to async trees??


Hi!
I'm currently working on a project in wich I use a pair of trees. The
thing is that one of them is too big and IE6 (it needs to be
supported :s ) takes forever to process the tree so I want to load it
asynchronously branch by branch using the async version of the tree.
The problem is that I want the tree to be a filetree, but when created
as async it displays with default style. Is it possible to create an
async filetree (without applying the classes "manually")??
Here's my code:
//js
    $(document).ready(function(){
        $("#tree").treeview({
            url: "MenuTree.aspx",animated: "fast",collapsed: true, unique: true
        })
    });
//html
    <ul id="tree" class="filetree">
    </ul>
Thanks in advance!
