<P>=0AHi<BR>=0A<BR>=0AI am currently using Mapserver 4.0 with PHP/Mapscript=
 and GDAL on RedHat Linux 9.0. <BR>=0A<BR>=0A1. My first problem is how to =
use shape file and a few .AVL files associated with that shape file to disp=
lay different maps and their corresponding legends. In ArcView, when i view=
 the shape file with different attributes layers and corresponding AVL file=
, i get different maps and color legends. How should i do this in mapserver=
 ?<BR>=0A <BR>=0A2. Currently, we have a few layers one after the other, bu=
t as we are planning to have many layers, we would like to show as files wi=
th in a folder. <BR>=0AFor eg.,<BR>=0A&nbsp; &nbsp; + Road<BR>=0A&nbsp; &nb=
sp; &nbsp; &nbsp; - Interstate<BR>=0A&nbsp; &nbsp; &nbsp; &nbsp; - State Hi=
ghways<BR>=0A&nbsp; &nbsp; &nbsp; &nbsp; - Local roads&nbsp; &nbsp; &nbsp; =
 <BR>=0A&nbsp; &nbsp; + Water<BR>=0A&nbsp; &nbsp; &nbsp; &nbsp; - Lakes<BR>=
=0A&nbsp; &nbsp; &nbsp; &nbsp; - Rivers<BR>=0A&nbsp; &nbsp; So, if i click =
on Roads, it should expand and show the 3 layers under it with checkboxes. =
Otherwise it should be just displaying Roads and not the layers under it. H=
ow can we do this ?&nbsp; &nbsp; <BR>=0A<BR>=0AI have been looking on the g=
oogle for a few days but couldnt find anything useful. And we are in need o=
f finishing this very soon.<BR>=0A<BR>=0ACan anyone help me on these issues=
 ? If possible can you send me some example code or may be as to how to app=
