Once I have loaded the layers into my application, is it possible to re-order their hierarchy? For example move the roads on top of the streams or move the parcels under the roads.
I have already found that I cannot change the transparency of just one layer, and can only adjust for all layers at once. My guess is that it is not possible to reorder the layers from the browser.
If this is the case how should I suggest my clients reconfigure their map server? Should each layer they want in the application be an individual mapService? Any other suggestions?
