Is there any reason to keep it there, like for external filters? If so, that still conflicts with the second example below. First off, it is invalid since there are some categories available. Second, having both '''show_option_none''' and '''show_option_all''' displays both entries. Related to #21856 trying to list only visible terms." enhancement closed normal Taxonomy 2.1 normal wontfix
