I add code like this， it could display in the post edit screen.
But when i add new tag in it, the post couldn’t save the tag. How to fix it?
Thanks for help~~~

function myplugin_add_custom_box() {

add_meta_box('tagsdiv-depart','depart','post_tags_meta_box','post','side','core',array( 'taxonomy' => 'depart'));

}

add_action( 'add_meta_boxes', 'myplugin_add_custom_box' );
