.. _Menu-get:

==============================================
Menu::get()
==============================================

\\nn\\t3::Menu()->get(``$rootPid = NULL, $config = []``);
----------------------------------------------

Returns an array with a hierarchical tree structure of the navigation
returns. Can be used to render a menu.

.. code-block:: php

	// Get structure for current page ID (pid)
	\nn\t3::Menu()->get();
	
	// Get structure for page 123
	\nn\t3::Menu()->get( 123 );

There is also a ViewHelper for this:

.. code-block:: php

	{nnt3:menu.directory(pageUid:123, ...)}

| ``@param int $rootPid``
| ``@param array $config``
| ``@return mixed``
