Given a document with several sections (say 4), each section can be very long. I'd like the user to have the option of "expanding" a section, or keeping it "compressed" within the document. It looks like <!--#tree--> would be able to do this if I could provide a suitable branches and leaves function. What I'd like is a document that looks like this: Header info always the same + Click to see detailed part A + Click to see detailed part B + Click to see detailed part C A user could have clicked on section B, so then they'd see + Click to see detailed part A - Click to hide detailed part B Here are the details in part B ... + Click to see detailed part C The tree elements would need to be in a document. It would be nice if it didn't need real leaf elements, but I could put parts a,b and c in other documents within the folder that holds the main document. Anyone have any suggestions how I could do this? How is "expr" used within #tree ? I couldn't find any mention of it in the source..
