How to make the value of one select box drive the options of a second select box

Question

I want to make an HTML form with 2 select boxes. The selected option in the first select box should drive the options in the second select box. I would like to solve this

Answer 1

You could do plain javascript. If this is all you need javascript for, then jQuery is probably too much.

create a function in the that populates the second combo box. In the first combo box, you call that function with onChange=theFunctionYouCreated()

hope that's enough to get you started.
