How to hide tree items which do not have a title? As a newbie I still have some problems in understanding when to use objectnames, functions, namespace-prefixes in different DTML attributes. So after going through all the documents about the tree-tag, I could not figure above out via trial&error... What I understand is a) that it has to be a certain expression either in the expr, branches oder branches_expr attribute (but which?) b) it has to be more that just smomething like expr="title", within the tree-tag, because _this_ title in particular is only one specific (the one of the document the tree tag is in) c) To get the title of each iteration-object in the tree, I have to put a function somewhere in the tree-tag, which retrieves the local title of the current tree-object (but I couldn't figure that out.. getattr() or getitem()? what syntax?) Any hints welcome... Oliver .. Oliver Wrede .. owrede@khm.de .. Academy of Media Arts, Cologne .. Peter-Welter-Platz 2 . 50676 Koeln, Germany .. http://www.khm.de .. ICQ# 6580315 ..
