I have created a front end post with a form and I would like to have several categories for the user to choose between. But the problem is that the dropdown category only show those categories that are in use. I need it to show all categories even if they are not in use.
The code I'm using is following:
wp_dropdown_categories( 'show_option_none=Kategori&tab_index=4&taxo. nomy=register_vote_category' );
