I have a migx with main-categories (the user can add or delete categories). I want to use the output of that migx into another migx in a listbox so the user can select a main-category and add a product to it. How to do this? I know how to make a listbox with static data, but I want the data to come from a migx.
Also what happens with the products under a category if that category is deleted by the user?
@Bruno17: this works, but one small question: I read on the official php website that the use of EVAL is dangerous. (http://php.net/manual/en/function.eval.php). Is it a risc to use it in this case?
