I want to remove or hide Categories / Tags submenu under Posts in the Admin Menu. I know this works with the themes submenus:

remove_submenu_page( 'themes.php', 'widgets.php' );

The same doesn't seem to work for posts unfortunately:

remove_submenu_page( 'edit.php', 'edit-tags.php' );

I'm using the admin_menu action: add_action( 'admin_menu', 'function_call' )

Do I need to add something else?

add_action('admin_menu', 'my_remove_sub_menus');

function my_remove_sub_menus() {
    remove_submenu_page('edit.php', 'edit-tags.php?taxonomy=category');
    remove_submenu_page('edit.php', 'edit-tags.php?taxonomy=post_tag');
}
  • I'm not seeing this hide the tag and category areas in the Quick Edit section, but I do so remove_meta_box working as described. – Spencer Williams Mar 14 '16 at 16:10
  • This is not the prefered method, its like removeing them using css, doesn't guarantee anything. check mbacon40 answer, it looks promissing. – jnhghy - Alexandru Jantea Oct 20 '16 at 21:49
  • @jnhghy-JanteaAlexandru remove_submenu_page does not use CSS to remove the submenu, it removes the entry form the global menu array (see source) so the HTML markup for the menu is not rendered at all (and not CSS-hidden). However, it is true that in some cases it may not prevent users from accessing the screen for the removed submenu directly (see ticket #18850) but OP asked to remove the menu, and it is the way to go. – gmazzap Oct 24 '16 at 9:25
  • @gmazzap I was makning a comparation. Removing it this way will not ensure tags are not added by other means ( front end ), I was trying to point out that this removes only the menu entry and not the post type connection to the taxonomy. :) – jnhghy - Alexandru Jantea Oct 24 '16 at 10:15

If you want to completely remove categories and tags you can do so like this:

// Remove Categories and Tags
add_action('init', 'myprefix_remove_tax');
function myprefix_remove_tax() {
    register_taxonomy('category', array());
    register_taxonomy('post_tag', array());
}

You may also want to remove the meta boxes from the Post Creation page

// REMOVE POST META BOXES
function remove_my_post_metaboxes() {
  remove_meta_box( 'categorydiv','post','normal' ); // Categories Metabox
  remove_meta_box( 'tagsdiv-post_tag','post','normal' ); // Tags Metabox
}
add_action('admin_menu','remove_my_post_metaboxes');

Thanks to @mbacon40 and to @gmazzap I was able to use this to remove Product Tags and Categories (product_tag and product_cat) from my menu and from the product add/edit pages.

// Remove Categories and Tags
add_action('init', 'myprefix_remove_tax');
function myprefix_remove_tax() {
    register_taxonomy('product_cat', array());
    register_taxonomy('product_tag', array());
}

add_action('admin_menu', 'my_remove_sub_menus');
function my_remove_sub_menus() {
    remove_submenu_page('edit.php', 'edit-tags.php?    taxonomy=product_cat&post_type=product');
    remove_submenu_page('edit.php', 'edit-tags.php?    taxonomy=product_tag&post_type=product');
}
