I am trying to organize my attribute table so that I can effectively create "drop downs", or "subfolders".
For example:
I have location x, location y, and location z associated with New York 1, new york 2, and new york 3....but what I really need is:
Location x, location y, and location z only associated with New York, such that when I select New york in the attribute table, I can click a kind of drop-down and see location x, location y, and location z.
This would really clean up my attribute table.
Any ideas? Let me know if you need more clarification.
