I currently have a 5 select boxes search feature which works fine.

However, I want to use AJAX so that only the content required by the user, is brought in from the db instead of all of it, as is currently the case.

Silly question time I suppose...can this be done such that each of the five 'boxes' is a select drop down? so you click a specific in select 1 to see the choice in the second select etc.
