HTML Tree View with <ol> and <a href>

[Larry Bates]

While not EXACTLY what you outlined, I've used TreeView
http:www.treeview.net along with Python to create the
dynamic tree menus you describe.  I had to write a
couple or very short JavaScript additions, but it is
working just fine.  All the tree opening and closing
is done on the client via-javascript so it is very
fast.
