   HI All,

   I googled and search for my answer but couldn't found it. I hope some one will help me here.

   Well, scenario is that i have created a custom post type and registered with it a custom taxonomy. Now problem is that on manage post screen of custom post type i am unable to get the select box used to filter the posts through taxonomy / category, which in default post is used as category filter.

   Thanks

   This adds a new colomn with the taxonomy name and link:

   register_post_type( 'book', array(
   	'labels' => array(
   		'name' => 'Books',
   		'singular_name' => 'Book',
   		'add_new' => 'Add New',
   		'add_new_item' => 'Add New Book',
   		'edit_item' => 'Edit book',
   		'edit' => 'Edit',
   		'new_item' => 'New Book',
   		'view_item' => 'View Book',
   		'search_items' => 'Search Books',
   		'not_found' => 'No books found',
   		'not_found_in_trash' => 'No books found in Trash',
   		'view' => 'View Book'
   	),
   	'public' => true,
   	'capability_type' => 'post',
   	'hierarchical' => false,
   	'rewrite' => true,
   	'query_var' => true,
   	'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'custom-fields', 'comments' ),
   	'taxonomies' => array('category','post_tag')
   	)
   );
   register_taxonomy(
   	'book_category',
   	'book',
   	array(
   		'hierarchical' => true,
   		'label' => 'Categoriën',
   		'public' => true,
   		'query_var' => true,
   		'show_tagcloud' => true,
   		'rewrite' => Array(
   			'slug' => 'book_category')
   		)
   );
   function add_new_columns($defaults) {
       $defaults['book_cats'] = __('Categoriën');
       return $defaults;
   }
   function add_column_data( $column_name, $post_id ) {
   	if( $column_name == 'book_cats' ) {
   		$_posttype 	= 'book';
   		$_taxonomy 	= 'book_category';
   		$terms 		= get_the_terms( $post_id, $_taxonomy );
   		if ( !empty( $terms ) ) {
   			$out = array();
   			foreach ( $terms as $c )

   			echo join( ', ', $out );
   		}
   		else {
   			_e('Uncategorized');
   		}
   	}
   }
   add_filter( 'manage_book_posts_columns', 'add_new_columns' );
   add_action( 'manage_posts_custom_column', 'add_column_data', 10, 2 );
