I have data validation for a drop down list with a condition with the named ranges to populate the dropdown:
IF(A2 = "1", List1, IF(A2="2", List2, ListAll))
This was great while we had limited number of lists. Now I have 10 lists and there is a limit in the Data Validation source box.
What is the best way for someone to choose an option in Column A and have Column B produce the corresponding list? I was trying to do a VLookup, but can't do it with data validation.
I want to make subtle changes and prefer not to add combo boxes, etc.
Any suggestions?
