[mapserver-users] drop down menu question

[Drake Steven T DPW ENV NAT RES ITAM(n)]

Let's try this again....

I would like to add a drop down menu with many choices of data layers to
display. I would like the user to have the option of choosing none, a
combination, or all layers, and keeping them 'on' through re-draws until
toggled 'off' from the same drop down menu. Any suggestions how to go about
this?

Thanks in advance,
Steven Drake
