I would like to see the following expanded capability of app interactive features. I would like to be able to select a group of layers that would enable users to select one from many layers. This would work similar to HTML form radio buttons. There are situations in which the map is confusing when the user selects more than one layer at a time. It would be nice to be able to create groups of layers controlled by radio buttons. Is there a way to do this now? Have I overlooked something?
