Organizing attribute table

[Anonymous User]

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.

Do you want to write a separate application to do this? since that capability doesn't exist in the current table structure.  You can query, sort etc and use the tools on an open table's toolset

Thank you! That's what I needed to know.
