[Zope] Name of top level folder

[Alex.Thomas@dresdnerkb.com]

Ah, brilliant - the expr keyword comes to the rescue. Many thanks, don't
think I would have found that for a long time.

As I'm now indebted to you and the list, I might make the very modest
contribution of the DTML that makes the multiline tree headings line up
neatly. Well, it's a start...

cheers

You might be confusing "name" with "id" or "title". You're right, the
root object does not have a name, but that should stop you from
including it in iterations, or the tree tag.

To tell the #tree tag to start at the top, do:

  <!--#tree expr="PARENTS[-1]"-->
    <!--#var title_or_id-->
  <!--#/tree-->

Note that, for obvious reasons, the top level will not be included in
the tree. (If you're wondering how the hierarchical tree seen in the
Zope management screens manages to include the root object, this isn't a
trick performed just with the #tree tag. See
zope/lib/python/Ap/menu.dtml for the DTML code.)
