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!

openlayers.org/dev/examples/controls.html has both checkbox and radio buttons – Mapperz♦ Oct 9 '12 at 16:54

Does this example do what you want? Or are there specific customizations you need on the layer control?

Seems to work on Safari on a pc - though not tried it on an iPad.

The BaseLayers section of the LayerSwitcher are exclusive (use Radio Buttons) by default. This example does not have any Overlays. I need to make the Overlays exclusive like the BaseLayers. Thanks! – cbursk Oct 9 '12 at 17:53

For Grouping Layers in Openlayers use GeoExt Tree

Interesting - I will check this out. Any ideas on how to make the Overlays exclusive? Thanks for your reply! – cbursk Oct 9 '12 at 18:06
After reading further about GeoExt, it seems this will not work for me. GeoExt requires also using ExtJS which requires buying a license, which I won't be able to do. I need to stick with free open-source software. Thanks for the reply though. – cbursk Oct 9 '12 at 18:18
