[Zope] [Fwd: Anyone know how to pre-expand a certain branch of a dtml-tree?]

Hello: I want a certain branch of my dtml-tree to be pre-expanded whenever the webpage that contains the tree is displayed. My dtml-tree is quite simple; I use the usual subordinate folder structure setup: <dtml-tree single=0 name="catalog" branches="objectValues"> TIA! --Craeg
