I have a need to filter the drop-down options in a cascading drop down with PHP code. I have been looking for an example of how to use the $opt->value, $opt->text in the (eval) option of the element. I've been able to figure out how to alter an option this way but what I really need to do is to remove it. Ideally, I'd like to add one if necessary. I've tried using $options but I can't see to get that to work. I'm not finding tutorials or examples. Can someone point me to some information about how I can use PHP code to remove some options from the drop-down?
