Question

I have a register form in which i want when the user selects an item from a first Select to create dynamically a second select with items from the database which are compatible with first selection.
For example i have 2 select Lists the first with Lessons and the second with professors.When i select from the first Select a lesson the Second Select Lists must have only professors of this lesson.
I am using jsp,java and i want to avoid ajax is this possible?
Thank you!

Yes it’s possible.

However without AJAX, you would have to load all of the data with the page. That means storing the list of professors associated with each lesson in either a Javascript array or in a hidden HTML element from which you can retrieve the data later on.
