Hello D-flyer

You can check the following links.

With mootools-

With ajax-(IMO this tutorial is best because they have shown it properly that how to use it.)

Using JavaScript (jQuery if you like), attach a function to the change event of the select box which sends its value to a PHP script via XMLHttpRequest (AJAX). Your PHP script reads that value (from $_GET like any other request), does the database query to get the items for the other list, and returns them in some format – JSON is probably a good idea using json_encode. Then the success handler function for your XMLHttpRequest uses this array to populate the second list.
