we can get you the legend used in that example if you wish.  There are 
two legend widgets that are available in Chameleon ...


this widget provides access to the HTML Legend Template functionality of 
MapServer.  There is considerable flexibility in this approach since it 
allows you to generate text in any format you wish ... I have seen some 
very cool DHTML implementations that provide the kind of multi-level 
grouping that provide the tree-like functionality you are interested in.

The limitation of the HTML Legend Template is that MapServer only 
supports one level of grouping and it is based directly on the map file.


This widget avoids the use of MapServer's legend template and was 
written for use in an OGC environment since the portable document format 
for OGC applications (Web Map Context) does not support any type of 
grouping or themes.

This widget allows you to define groups of layers and place them in 
themes, and uses a similar templating system as the HTML Legend 
Template.  It is way more flexible, but also more complicated (and there 
is far less documentation right now).

Because of the templating approach, you can also create complex DHTML 
effects with this widget.

HTH ...
