[Zope] Help needed in getting HierMenu to work

Hi Has anyone had success using the HierMenu listed at http://www.zope.org/Members/Ioan/ZHierMenus It seems to use the HierMenus at http://www.webreference.com/dhtml/hiermenus/ I would rather use this Javascript menu system using Zope in place of just putting the Javascript in the page and manually setting the menu. Maybe someone has got it working and I have missed something? I am using Zope 2.3.3 (binary release, python 1.5.2, linux2-x86) regards Greg
