I already post my sample workbook. Would you please take a look and give me some suggestion? Thanks
The sample workbook was not there originally, from what I remember.
The quick filter and what you select on the map are not really the same thing, so I'm not sure what you are trying to do is possible. The filter just filters the data available in the view, and determines what counties can be shown on the map--the filter list has nothing to do with what counties someone clicks on in the map itself. Actions and filters are treated separately, as far as I know (and I'm not an expert so maybe someone else can better answer your question).
If you are saying you want the filter selection on the right to update based on what is clicked on in the map itself, I don't think it is possible--but I could be wrong. Again, I'm fairly new to Tableau myself.
I do understand why you'd want to do this. But--why not just eliminate the filter selection on the right, and use only the map for filtering? Is there a reason to show the filter list in the first place? Just thinking out loud. If it were me, I would just explain to my users that the list on the right doesn't reflect choices made in the map itself.
Thanks you very much.
