I have a series of cascading dropdownlists. When the first one is changed, the second is updated based on the selection from the first list. I would like for the 3rd and 4th to be reset to a blank list until the user selects a value from the second list (which will fire its change event and repopulate it). I've tried to add the following in the change event for the 1st dropdown as I've seen on another forum post, but nothing is hidden when the event fires. Is there a way to just clear out all of the entries in the list? I didn't see a method in the doucmentation that appeared to do that.
