Only 2 ad categories appear on new ad form
I have created a hierarchy of ad categories however when you post a new ad only the first two levels appear on the new ad form. This does not allow a user to select any of the categories below the first two levels.
I believe the categories can be up to 10 levels deep, does anyone know how to enable all levels to be accessible from the new ad posting form?
I'm sure there is a very simple answer but I am very new to all of this.
