help with forms

[corruption]

I have a form that i want processed for each type of user.

one of the fields is a drop down list. Depending on the selection there i want a list of other questions to come up.

i'm not sure how to do it though.

for example

if they selected alumni one set of questions would appear.

if they selected brother than another set...and so on.

Any ideas

Javascript onClick might be a good one... onClicking particular choice it reloads page with options related to previous selected option
