Need to create one parameter with reference of 2 columns
I need to create a parameter, in which I want to put two values, let's say A and B are the values, now A value will linked with column 1 and B value will linked with column 2. So that at dashboard, if I select value A in the parameter, I can see data of column A and same goes for B. Is it possible in Mode? If yes, please let me know.
