In my dashboard, I have a polygon map of city council districts. When a certain district is filtered for on the dashboard, I want a text box to pop up on the map saying 'This district is blah blah'. I only want it for one district. When any other district is selected, no text should show up on the map.
I've tried using annotate and tooltips but those appear regardless of what district is selected in the filter.
I'm on Tableau 2020.4
