I have a Openlayer web map with LayerSwitcher con开发者_运维问答trol added. I need this to switch some of my layers. But I am also adding and removing some layers, which are temperory and i donot want them added to the LayerSwitcher Control. So is there a way to add layer to OpenLayers, but without it getting automatically added in LayerSwitcher Control?

Figured this out. I need to add 'displayInLayerSwitcher: false' in the layer options.
