I understand that child-categories will not show in a form if the Parent-Categories are excluded (is this correct?). The problem in showing parent-cat and its sub-cats is that my users may click the parent, whereas I need them to chose from the subs. See attached image .
So I need to hide, or ‘mask’ the parent – perhaps just adding a white label on top of the parent area so it is not visible to the users? Or maybe just changing the parent text colour to white (and its checkbox to white as well) so it is simply not visible at the frontend?
