I have 30 layers in my WebMap. The default is to have all 30 layers turned on. Instead of a user to have to go into the Layer List Window and turn 29 layers off, so they can view that 1 layer they want by itself, I want a user to be able to use a drop-down list to choose which layer they want to see. When these user selects a layer from this list, then the only layer they will see in the map window is the layer they selected from the drop-down list.
I know the eSearch selects features and this highlights them.
