I am trying to setup a WMS that consists of 6 layers of thematic maps on GeoServer. I tried to add LayerSwitched() to the code but the map just went blank. My question is: is it possible to add LayerSwitched for a Layer Group of WMSs? If no, is there another way to show 6 layers of thematic maps (somehow at the same time) on GeoServer?

The reason your map becomes blank it’s because the OpenLayers library provided with the Preview page doesn’t include the LayerSwitcher control.
Trying to load that Control breaks the code execution, preventing the loading of the map.
As you can see in the source code, there is a comment to warn you about that.
I hope this helps.
