I want to be able to choose ONE column and also have L and M columns shown. Column A,B,C will always be visable.
Example: User want to display Column "D", they would enter "D" into the field B2 and the sheet would hide Everything except "D" and "L" and "M".. Also keep in mind that "D" could be any column chosen.... E or F or G etc..
L and M of course will change later as the sheet grows.
I wish slicers could work this way across rows.
