Hello all, I am trying to add an Extent Indicator in a Map Series (mapbook) in Pro. I have successfully added one, but it does not act independently of the main Map Frame. Example: when I click to turn off roads in the Extent Indicator, my roads layer turns off in the main Map Frame also. I have tried right clicking on the the Extent Indicator map ->Properties->Options->Locked. I have tried right clicking on the the Extent Indicator map ->Activate. How can I make the Extent Indicator work separately from the main Map Frame? In ArcMap, all I had to do was R click on the inset map->activate and then I could turn layers on/off without affecting the main map. How do I do that in Pro? Any help is appreciated! - Catherine.
