My problem is I would like to pick one and only one of each. Let me explain using superstore, since my data is in the same structure. From furniture, you can only pick 1 sub-category (this would be like 'Actual' in my data), and you can only pick 1 from Technology (this would be like 'Actual' in my data). so my dropdowns for selection would be
Actual- (Bookcases, chairs, furnishings, tables) and Plan (Accessories, Copiers, Machines, Phones).
Again, thank you in advance. The Tableau community is awesome.
