He reads all from local database, and I'm trying to find a solution for my problem... Language is Serbian, I have a Driving school where user will select category that he wants, then he will select driving school from combo box, and then he will have choice to select driver instructor who works at that school...

I'm not very familiar with JSP codes. Are you having issue fetchin the data from the database or displaying it?

I think you need to do something like this:

I can display all of them. (3 combo boxes). But I need to disable one of them, until some choices from other combo box are configured. (First, I need to choose Driving school that I want, and later depending of which school did I choose, I need to get instructors who worked there- I already make instructors and tell in which school they work)

At the moment, I see all instructors from all schools, and I can insert it in that way in my database, but it doesn't have any logic, e.g. my instructor Kevin works for school DRIVING, and my candidate selected another school, and chose Kevin for his instructor
