As I don't see these pages on ZDP, here is the code you're looking for by 
email:

<!--#tree Outline branches_expr="objectValues(['Folder', 'DTML Method', 
'DTML Document'])" nowrap=1-->
<A TARGET="?" HREF="<!--#var URL2-->/Outline/<!--#var 
tree-item-url-->"><!--#var title_or_id--></a>
<!--#/tree-->


The tag selects the acquired Outline object as a base, and specifies that 
it wants all Folder, DTML Method and DTML Document objects to be branches. 
The URL is constructed using the URL of the documents second parent. If the 
document you place this in is a DTML Method, that probably should be URL1, 
I did it with a DTML Document, and then it is URL2. Finish off the URL with 
the /Outline/ part and the URL to the item displayed.

You will have to fill in the TARGET attribute, as I did not know the name 
of that subframe.

You might want to add icons, like the open and closed books. Look at 
lib/python/HelpSys/helpsys_menu.dtml for ideas.
