I would recommend to you to use prepared components for JSF

Try PrimeFaces.

They have a table with an option to filter.

See a demo of database with the filter option here

Try AJAX. When the first selection fires off an event, make an AJAX call back to a service to query the database for the second drop down values using the selected value.
