I created a custom taxonomy called "portfolio" and added the tags column to the custom post type using:
register_taxonomy_for_object_type( 'post_tag', 'portfolio' );
After I add the tags widget to the sidebar, the tag cloud shows all the tags from all my posts. How can I show tags that belong only to the "portfolio" taxonomy?
Also is there a way to change the default name "Tags" for the portfolio taxonomy to "Portfolio Tags"?
