You can have 2-level structure:
categories
+ groups
multiple layers can form a group but not visible to the user. Categories are
currently only for thematic ordering, you cannot switch on/off all groups of a
category at one click. I'll put that in a future version since I found now a
way to have it appearing logical and not too confusing to me.
More levels than this structuring have to be developed by yourself because I
find it way too complex to understand and I'm not planning to implement it.
Since the whole layer/TOC/legend display is quite separate from the map
display, the only thing you will have to modify is the list of groups/layers
you want to display (using the setLayers() function in mapserver.js and update
the session variable for that. How you get that list is up to you.
