Hello I'm looking for a code that can guide me to generate four chained selects with data from mysql database, that let me add new rows to a table that maintain the same logic of the four chained select with data from mysql when I do click an add row button and so on.

Anyone can give me a link or download site that I can use to build that I want? Could be a JavaScript, jquery, php that let me do what I want in HTML.

Best Regards
