dynamic drop downs... sub drops

-

i'm thinking of adding feature site users can narrow search results using drop downs, , sub drop down options based on first selection.

for example:

country dropdown... user selects country , gets states dropdown... user selects state , gets city dropdown. state options within country, , city options within state.

any ideas on best way this... or there better approach together?
