Hello Gurus, Newbie to PHP here. I have a list of categories, as checkboxes, that I would like a user to be able to choose from. There are literally hundreds of categories, however most of them are children categories. I obviously don't want to display all of the categories at once to the user as that would be unwieldy. What I would like is for the user to select the desired checkbox and then all the children categories would display. The categories are setup as follows: Basketball and Football are the root categories. Once one of these are selected, it would be expand to show the conferences and once the conference is selected it would expand to show the teams. Example: Basketball ACC Big 10 Wisconisin Illinois Michigan . . . Big 12 ACC . . .
