How Do I Show Custom Post Type Categories in WordPress?

When creating custom post types in WordPress, you may want to show them as categories in the WordPress admin. This can be done by setting the custom post type’s show_in_nav_menu setting to ‘true’. To do this, open the wp_options table in the WordPress admin, and enter the show_in_nav_menu parameter for the custom post type as follows:
