Using AJAX is a great way to do what you are asking.

Please forgive me if you already know this but in jQuery/javascript, you:

• grab the value of the first select box

• use AJAX code to send that to a secondary PHP file, which uses the data it receives to write some HTML code based on what the user chose

• the newly constructed HTML is ECHOed back to the ajax routine, where it is received inside a success function

• Inside the success function, you can use jQuery to replace the contents of the second dropdown

Here is a detailed example, with explanations
