JavaScript: jQuery: Dependant Selects Tutorial

A dependent select is when a form select box's options depend on the values of a previous form select box. Two examples of this would be a USA State selector, which then filled the next box with cities from that state. Another example would be a car make selector (ie. Ford) which then displayed models (ie. Taurus, Bronco, F-150). In this tutorial we're going to create a dependent selects plug-in using jQuery.
