Take a look at this forms generation and validation class. It comes with
linked select plug-in class that does exactly what you want.

It lets you define select inputs with multiple groups of options that
are switched dynamically when the value of another input changes.

There is a static version of the plug-in that lets you define the
alternative groups as an array, and there are several variants of the
plug-in that picks the groups options from a database using different
API: MySQL or database independent with Metabase or PEAR::MDB2 API.
