Hello Zopeople, I found the menu suggestion below by Tino very good (exactly what I have been trying to do for the last week). I would like to modify it slightly thoughÂ… and can not get it to work. Can someone please help me out? How do I traverse the folder hierarchy of zope stopping at the first object with the property menue_root (I have it built into a folder like ZClass). I am trying to search *upwards* until I find the first object with a menu_root property (I want to make the sidebar menu start at a folder below root for departments of my faculty below the central pages)?

Hi Robert,
I do this and I dont use the tree-tag at all anymore. The trick is to organisate your site hierarchically. I do only folder-like objects with one content-object (or property or whatever). So the site is simply a tree of folderobjects (not folder itself but a subclass (or more then one subclass of it)) Then a simple method can render the navigation: (lets call it navigation) <table> <dtml-in "objectValues('TheFolderClass')"> <dtml-if "sequence_item in PARENTS"> <tr><td>[-]</td><td>&dtml-title;<br> <dtml-var navigation></td></tr> <dtml-else> <tr><td>[+]</td><td><a href="&dtml-absolute_url;/">&dtml-title;</a></td></tr> </dtml-if> </dtml-in>
This is the very simple approach, you can make more design if you want. The trick is "sequence_item in PARENTS" which is true if the actual object is in your URL path. This way the tree shows your current navigation without bothering to save the treestate or bother the user with ugly cookies and/or URLs.
I have to mention you must call this "navigation" method inside a index_html method or something you let acquisite. Call is there like that:
<dtml-with "PARENTS[-1]"> <dtml-var navigation> </dtml-with>
To start the tree at the root.
Oh, you have to use "_['sequence-item'] ... " and stuff if you dont use my dtml-in replacement.

Hope someone has already run into this: I need to be able to control the tree display state from dtml and I can't find any info on the subject.
The "normal" tree display has the "+" (or "-") part, with its own URL that includes an encoded argument, and the user-defined part. At the very least I would like to be able to mimic the behaviour of the "+" by clicking on the "user" part (which I make into a link by myself). To make matters worse, this link may take me to another object (page).
Ideally, I would like to be able to control the display behaviour - saying which branch(es) are to be shown open and which closed, and to which level, within the page itself.
Any pointers would be greatly appreciated. Tnx,
Robert
