Create a set of custom filter options not in list of values

[sarah_hussain-1]

Hi there,

In tableau you can create sets from values, and then use those sets to define a new list of options from a filter.

For example in tableau, I could create the following expression:

CASE [metric] WHEN 'd000' THEN [age] = 'd000'

WHEN 'd001' THEN [age] = 'd001'

WHEN 'd002-d003' THEN [age] = 'd002-d003' 

 WHEN 'total' THEN [total_dau]

WHEN 'returning' THEN [returning_users] END

I am not sure how to use the custom filter option in the explore to recreate this expression

Thanks!
