Today we will talk about creating dependent (chained) selects for your projects. This can be any related elements at your website. As example dependent fields to select your profession, mobile phone, or location (which can include Country, State, Region etc). One important note – we will need all this working using AJAX technology (to make functionality fast and smooth). And, jQuery library provide us with that plugin – jquery.chainedSelects.js. I will show you how to create chained fields using this plugin.
