Change data displayed via Pop-up menu
I have a long list of data that needs to be narrowed down. Is there a formula/function that will change the data displayed as determined by a pop-up menu? For example:
If I were to choose "Brown" from the above pop-up menu, only the entries whose hair is brown would be displayed (ie. Bilbo and Gimli); all others are hidden/not shown. To complicate matters, I have data in two different columns that I need to narrow the list by: in this case, the color of their hair, or the number of letters in their first name.
Using Numbers 3.6.1 in El Capitan. Thanks in advance for your help.
