He creado un Tipo de publicación personalizado llamado 'listing'y agregué una Taxonomía personalizada llamada 'businesses'. Me gustaría agregar una lista desplegable de empresas a la lista de administradores para los listados.
Así es como se ve esta funcionalidad en la lista de administración de publicaciones (me gustaría lo mismo para mi tipo de publicación personalizada):
Aquí está mi código actual ( y aquí está el mismo código en Gist ):
<?php

Hay un complemento Admin Taxonomy Filter que puede hacer el trabajo exacto.
