[Mapserver-users] HTML Legends as lists

[Liz Godwin]

Stephen,

That's nice and all, and looks like I want it, but from a first glance,
doesn't look very dynamic based on the map object.  I don't want to have
to manually make a legend.  It should be built from my mapfile.  I
didn't read the article in great depth, so if I missed out on this very
thing, I'm sorry.  

Liz

Liz,

this may not be exactly what you want but if you want a tree to display
the
layers that is collapsible have a look at:
