[OpenLayers-Users] Question on having multiple layers

[Ali Khan]

Hey, presently we're developing a system that will have MANY layers 
we're talking 20-50.

I know in OpenLayers you need to setup a name etc for each layer. I was 
thinking using a loop to output each layer (the basic data ie layer name 
etc is stored in a backend database). Still when somoene opens up the 
navigation tab though it can become quite long.

Is there anyway one can make a select box on the page and on change have 
it reference the appropriate layer to show in OpenLayers?
Also for each layer we want to have a seperate getFeatureinfo query as 
each layer contains different data. How do we do this? can we do 
layer.events.register instead of map.events.register for instance so 
that each layer has its own on click event?


Thanks.
