> If you have multiple maps, is it possible to have different widgets appear when a map is selected and to "dissappear" when another map is selected that doesn't use that widget??
This functionality is not possible with Ops Dashboard. May I suggest the following: why don't you setup a map element with its respective elements in one Dashboard layout, then setup the second map element with its respective elements - and stack this on top of the first layout? or you could have 2 separate Dashboards and "contain" them together in a single app, in a StoryMap.
Hope this helps,
