I don't have Tableau 10. I didn't understand the relation between this picture(category) and States.
I didn't understand what you want to see. Are two different views? They seems to conflict to me.
I want to be able to change view on a specific state if I want to (based on top 10 states) or have all values shown.
In my view and FILE if you check on state filter you will see the list is too long and I would want list to show only 10 top states (based on sales)
Is that more clear?
Find My approach like below :
Create a parameter with 2 values Top 10,All to choose which way we want out filter to be.
Then create a set for Top 10 list :
Create a calculation like below : I named it Filter .
IF [Select]='Top 10' THEN (IF [Top 10 State set] THEN [State] END)
Then just duplicate this calculation and drag Filter(copy) into filters shelf and exclude Null.
Then drag Filter into Filters shelf and choose show quick filter and in filter option choose to show only relevant values.
This step is to remove Null value from filter when we choose Top 10.
