Hi, I was trying to mimic the tree which you can see when you open the HelpSys. I would like to use it for our "ZBook" at ZDP. However I can't find the source of this, so I try to make it myself, but I've some problems, maybe someone can give me a hand? Ok. We've a folder 'Introduction', with sub folders 'zig_main', 'zig_menu' and 'Outline'. Then index_html of 'introduction' contains a frame page to 'zig_main' and 'zig_menu'. In Outline, I've put several subfolders with subfolders each containing a chapter of the book. What I want to do now is this : In subfolder 'zig_menu', create a tree from the contents of 'Outline'. This that all subfolders and documents titles are displayed. When clicking on a link in the tree the document the document is displayed in the main frame. I've already problems of creating the tree in zig_menu! :-( <!--#tree /Introduction/Outline --> <!--#/tree--> doesn't work... And how do I get all the subfolders and documents in a tree? Can someone help? Tom.
