I would like to answer my own question (see below). According to ZOPE/lib/python/TreeDisplay/TreeTag.py, there is no way to suppress the display of the + or - signs. However, there certain parameters to __init__ that have been commented out: # opened_decoration = None, # closed_decoration = None, # childless_decoration = None, which suggests that either there was a way to control this at one time, or that it is functionality that is planned for the future. What is the plan for this in Zope 2.5? I could prepare a quickie patch if you guys don't have the time. Please advise, thanks! --Craeg ] I want to display a dtml-tree always expanded, with no controls visible ] for contracting (basically, an indented list of links). ] I set the tree to always expand via the following: ] <dtml-call expr="REQUEST.set('expand_all', 1)"> ] <dtml-tree single=0 name="catalog" branches="objectValues"> ] But I can't figure out how to remove the little minus signs (-) from the ] branches. ] Has anyone done this? ] TIA, ] --Craeg
