@bustapaladin they're in the codex:
why does it add another category automatically?
when I publish the post it automatically creates another taxonomy in the list.
Hey eduardo..this is really great!!
I was wondering, is there a way to retain the add_new_item link that you normally get when you use register_taxonomy?
i.e.
'labels' => array(
'name' => 'Category Sorting',
'new_item_name' => 'New Category',
'add_new_item' => 'Add New Category',
),
Thanks so much for your help.

Do you know by any chance the default code? I want to edit a bit like add some echos here and there but not change it to a dropdown like the code above does.
