[Zope] Help with tree tag and localfs

[AM]

I am sorry, I probably didnt explain my setup properly. The functions 
that I use are for my use only. You dont necessarily need to use them to 
do what you want.

The minimal thing yoou can do is the following:

<dtml-let root="zinesfolder">
  <dtml-tree name=root branches_expr="objectIds()" nowrap single>
    <dtml-var id>
  </dtml-tree>
</dtml-let>

This will display your tree (with all the members in there).

If you do the following:

<dtml-let root="zinesfolder">
  <dtml-tree name=root nowrap single>
    <dtml-var getId>
  </dtml-tree>
</dtml-let>

This wil show all the folders int your LocalFS instance.

If you want more functionality please provide some more specs and mebb I can help
