At the simplest level I need to figure out how to create a customized OpenLayers LayerSwitcher Overlays section which is not using Checkboxes, but uses RadioButtons instead.
For my application its not desirable for the user to be able to select multiple layers. Eventually I'm going to need to be able to create group sections in the Overlay section of the LayerSwitcher, so if anyone has any hints on that I'd appreciate it.
I've seen the customized LayerSwitcher example on the OpenLayers site, but I can only get it to work in Chrome. I need to be able to support Safari on an iPad.
Thanks for any advice!
