HI All,<span style="display:block"><span></span> </span><br>
<br>
I am working on open layers and map file and I have a question. I am
trying to create several layers from 1 map file on open layers, and I
want to switch off and on but I couldn't separate the layers in
OpenLayers. When I set layers to DEFAULT in map file it displays all
layers together like a one layer. I can't create different layers from
one map file. Are there any ideas? Codes are below;<br>
<br>
