Re: Re: Dependent Dropdown Boxes

it is all .js right, but there are the js_products and the js_categories javascript variables which are server-side generated. They are dumped from the database and encode '|' seperated values. Btw, what you are achieving is heavily JavaScript...otherwise you can it almost all in PHP w/o javascript...which is reload the page everytime he chooses a new category. something like: panel Categories | panel subCats generate categories as: select * from categories generate subCats as: select * from subcats where cat={selected Cat} add an event to the categories listbox as: onchange="this.form.submit();" this will cause the form to reload and refill your subCats accordingly.
