I've definitely pulled my hair out on doing that sort of thing. A lot of it depends on HOW you are getting all the other options. I have a work order system that asks you to choose if the work order is for a building or vehicle. Then if you choose building it wants to know what section of the campus it's in. Then once you choose that, it gives you a list of the buildings in that area. My solution is a hack job but it works....

It's a lot of hiding and showing divs with js at the bottom.
