Adds a group to a toolbar menu node.

Description

Groups can be used to organize toolbar items into distinct sections of a toolbar menu.

Parameters

$argsarrayrequired
Array of arguments for adding a group.
  • id string
    ID of the item.
  • parent string
    Optional. ID of the parent node. Default 'root'.
  • meta array
    Meta data for the group including the following keys: 'class', 'onclick', 'target', and 'title'.

More Information

  • Toolbar items are also called “nodes”. Nodes can be parents for other nodes, which creates dropdown menus. When adding a group you’re actually adding a group node. Group nodes are not visible in the Toolbar, but nodes added to it are.
  • This function is a method of the WP_Admin_Bar class and $wp_admin_bar global object, which may not exist except during the ‘admin_bar_menu‘ or ‘wp_before_admin_bar_render‘ hooks.
  • The Toolbar replaces the Admin Bar since WordPress Version 3.3.

    Adding a group to a parent node

    This example adds a parent node, child nodes and a group to the toolbar.

    add_action( 'admin_bar_menu', 'add_nodes_and_groups_to_toolbar', 999 ); function add_nodes_and_groups_to_toolbar( $wp_admin_bar ) {	// add a parent item	$args = array(	'id' => 'parent_node',	'title' => 'parent node'	);	$wp_admin_bar->add_node( $args );	// add a child item to our parent item	$args = array(	'id' => 'child_node',	'title' => 'child node',	'parent' => 'parent_node'	);	$wp_admin_bar->add_node( $args );	// add a group node with a class "first-toolbar-group"	$args = array(	'id' => 'first_group',	'parent' => 'parent_node',	'meta' => array( 'class' => 'first-toolbar-group' )	);	$wp_admin_bar->add_group( $args );	// add an item to our group item	$args = array(	'id' => 'first_grouped_node',	'title' => 'first group node',	'parent' => 'first_group'	);	$wp_admin_bar->add_node( $args );	// add another child item to our parent item (not to our first group)	$args = array(	'id' => 'another_child_node',	'title' => 'another child node',	'parent' => 'parent_node'	);	$wp_admin_bar->add_node( $args ); }

    The output from this example in the toolbar will be:

     * parent node ** child node ** another child node ** first group node
