Dynamic dependant dropdown from database

BUT, I don't understand enough about JQuery to get it to work in CI, so I need some help please?

I know only a little Javascript, but I don't think there's anything special to get it working "in CI" because PHP doesn't interact with Javascript. By the time Javascript is ready to run, PHP has already finished. Can you get any Javascript to work in a page generated by CI? Conversely, does the Javascript code you have work ok in a regular HTML page you create by hand with just a few dropdowns?

Edit: I just found this. It may help. http://stackoverflow.com/questions/20483...enu-values

Hey, don't work without a PHP debugger. Several free IDEs have this features built in. Two are NetBeans and CodeLobster. Without a debugger, it's like you're driving with a blindfold on -- you are going to crash!
