[Zope] Re: Zope digest, Vol 1 #1363 - 51 msgs

[Carl Robert Blesius]

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 though=85 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)?

Carl
