I want to create a custom 'smart' form that changes according to what the user is selecting. Currently, I have it refresh everytime the user selects an option but that method is really slow. I noticed that
http://www.cars.com/go/index.jsp
has a form that does not refresh. I'm not sure how they do what they did. Any help??

Thanks in advance..

Tony
