Custom Menu metaboxes do not show in the /nav-menus.php page

[alexvorn2]

The problem: Custom menu metaboxes does not show for custom post type and custom taxonomy after fresh install.

Insert this code into the function.php file (of the Twenty Twelve theme):

function codex_custom_init() {
  $labels = array(
    'name' => 'Books',
    'singular_name' => 'Book',
    'add_new' => 'Add New',
    'add_new_item' => 'Add New Book',
    'edit_item' => 'Edit Book',
    'new_item' => 'New Book',
    'all_items' => 'All Books',
    'view_item' => 'View Book',
    'search_items' => 'Search Books',
    'not_found' =>  'No books found',
    'not_found_in_trash' => 'No books found in Trash', 
    'parent_item_colon' => '',
    'menu_name' => 'Books'
  );

  $args = array(
    'labels' => $labels,
    'public' => true,
    'publicly_queryable' => true,
    'show_ui' => true, 
    'show_in_menu' => true, 
    'query_var' => true,
    'rewrite' => array( 'slug' => 'book' ),
    'capability_type' => 'post',
    'has_archive' => true, 
    'hierarchical' => false,
    'menu_position' => null,
    'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
  ); 

  register_post_type( 'book', $args );
  

  // Add new taxonomy, make it hierarchical (like categories)
  $labels = array(
    'name'                => _x( 'Genres', 'taxonomy general name' ),
    'singular_name'       => _x( 'Genre', 'taxonomy singular name' ),
    'search_items'        => __( 'Search Genres' ),
    'all_items'           => __( 'All Genres' ),
    'parent_item'         => __( 'Parent Genre' ),
    'parent_item_colon'   => __( 'Parent Genre:' ),
    'edit_item'           => __( 'Edit Genre' ), 
    'update_item'         => __( 'Update Genre' ),
    'add_new_item'        => __( 'Add New Genre' ),
    'new_item_name'       => __( 'New Genre Name' ),
    'menu_name'           => __( 'Genre' )
  ); 	

  $args = array(
    'hierarchical'        => true,
    'labels'              => $labels,
    'show_ui'             => true,
    'show_admin_column'   => true,
    'query_var'           => true,
    'rewrite'             => array( 'slug' => 'genre' )
  );

  register_taxonomy( 'genre', array( 'book' ), $args );

}
add_action( 'init', 'codex_custom_init' );

2) Fresh install of WordPress;
3) Update permalinks;
4) Go to the "/nav-menus.php" page.

Expected to see two menu metaboxes, one for Books and the second for Genres.

Works perfect for me. Not sure what goes wrong for you.

Are they not turned on in screen options?

You have to open screen options and check the check boxes for both Books and Genres.

Works for me.

I never looked into there before, Thanks for the tip!

It works as MikeHansenMe has suggested.
