Remove menu item from WordPress admin bar

This is how you remove menu item from WordPress admin bar. In this case I want to remove the Notes menu item. Add this to your themes function.

// remove notes menu from the admin bar
function mytheme_admin_bar_render() {
	global $wp_admin_bar;
	$wp_admin_bar->remove_menu('notes');
}
add_action( 'wp_before_admin_bar_render', 'mytheme_admin_bar_render' );
