cool ... it only works in IE though ;)

that is correct.  We have tossed around some ideas for adding support 
for additional levels of grouping but never found anyone willing to pay 
for it to be implemented nor had a compelling reason to implement it for 
our own purposes.

JSTreeView is a utility widget that we added for the upcoming MapEdit. 
JSTreeView is pretty much an internal widget at this point, but 
essentially what it does is take the contents of a SharedResource widget 
and display it in a hierarchical tree using some js/dhtml based tree 
code we got from treeview.net (I think that was the URL).

The code for that might be in the common folder under jtree.  If not, 
then check out the php_utils project from maptools.org:

CVS root:

:pserver:cvsanon@cvs.maptools.org:/cvs/maptools/cvsroot

The module name is "php_utils"

There is no password

You can copy the php_utils/src/jtree folder from there to the 
htdocs/common/ folder and then the widget will at least have the 
javascript part ready to go

You would then need to build some javascript calls into your renderer 
file to build the appropriate javascript objects for the tree.  I have 
speculated on this a couple of times but never tried it.  Or write a 
widget that creates a sharedresource from the information you want in 
the tree.  Its kind of tricky though.  This will eventually be 
documented but this will probably be one of the last things to be done.

You are not permitted to use jtree outside of the scope of chameleon 
unless you purchase your own license ... but within chameleon we are 
permitted to distribute it royalty free.

Cheers,

Paul
