There is this kind of hierarchy in web programming:
XHTML->php/mysql -> javascript->DOM->XMLHttpRequest
What you want to do is keep the user on the same page even if he has to
use the third drop list. That means you have to keep the data available
to javascript/DOM/XMLHttpRequest.
AJAX is just a buzzword that encompasses dynamically refreshing pages
techniques.
Google search with these keywords + howto, and get going! :-)
