Does anyone have any info on this vraibale? The DTML guide mentions this as a variable that influences the dtml-tree tag, but is very vague as to what it does. I'm trying to produce a site-navigation tree to go down the left of the page. I've got the tree working now, the hard bit was: <dtml-tree expr="PARENTS[-2]" branches_expr="objectValues(['DTML Document','Folder'])"> which keeps the tree display anchored to a fixed point in the Zope tree. But I now need to ensure that the document being viewed is expanded in the the tree, so for example, if I'm viewing test.html in the /Test folder, I want the tree to look like: -Root -Test text.html not: +Root or -Root +Test if you see what I mean. Can anyone help? cheers, Chris
