Remove Categories / Tags From Admin Menu

The question:

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?

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

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');
}

Method 2

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());
}

Method 3

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');

Method 4

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');
}

Method 5

for some reason the edit.php does not work at my setup 5.3

This however works

remove_submenu_page( 'edit-tags.php?taxonomy=category', 'edit-tags.php?taxonomy=post_tag' );
remove_submenu_page( 'edit-tags.php?taxonomy=category', 'edit-tags.php?taxonomy=category' );
