More Information More Information

Depending on when this function is called, it may not prevent users from accessing the screen for the removed submenu directly (see ticket #18850). Removing a menu does not replace the need to filter a user’s permissions as appropriate.

In order to remove the theme-editor.php submenu of themes.php (and others) in more recent versions of WordPress, you need to bind to the admin_menu hook with a very high priority (about 110, depending on the submenus to remove). Don’t use admin_init as previously stated here, hence it will break wp-admin/admin-ajax.php.

    Sometimes it can be tricky to figure what combination of menu/submemiu slug is required to remove a submenu.

    You can figure it out by actually printing the global $submenu array to your debug.log file, and identifying the submenu you want to remove.

     global $submenu;
 error_log(print_r($submenu, true)); //this will print out all the menus/submenus currently available in the admin.

    Example
    Removes the Widgets submenu page.

    /**
 * Remove the Widgets submenu page.
 */
function wpdocs_adjust_the_wp_menu() {
	$page = remove_submenu_page( 'themes.php', 'widgets.php' );
	// $page[0] is the menu title
	// $page[1] is the minimum level or capability required
	// $page[2] is the URL to the item's file
}
add_action( 'admin_menu', 'wpdocs_adjust_the_wp_menu', 999 );

    In the above example, the value of $page would have been:

    array(3) { [0]=> string(7) "Widgets" [1]=> string(18) "edit_theme_options" [2]=> string(11) "widgets.php" }
