How are you storing the lists of data?
In a Database or hardcoded.

You've giot two options really,
either post the selected item in the first select box back to the server and re-queary the database using the data posted back as a key.

the other option is to load all the data into a client-side javascript.

Here's an example of what I mean

The first method is simpler but slower
