[UPHPU] Off topic: mysql + php + javascript dropdown lists..

Can anyone point me in the right direction for a how-to on this?  I just 
need to be able to make a few option lists, where if you select an 
option in list A, it pulls up that subset and displays it in list B.  
Prime example: http://utahrealestate.com/

I'd imagine this is a pretty standard trick but I'm not sure what to 
call it to search for it. Trying to point a user in the right direction 
here myself.
