How do I extend the Zend Navigation Menu View Helper?

$view->addHelperPath( APPLICATION_ROOT . ‘/library/MyApp/View/Helper/Navigation’, ‘MyApp_View_Helper_’ ); echo $this->navigation()->myMenu(); // name of your class From: Getting Zend_Navigation menu to work with jQuery’s Fisheye EDIT Sorry I’ve not seen your solution, it is exactly what I’ve posted. But why this is not a trully extension of menu class?
