Customizing Zend\View\Helper\Navigation\Menu

CustomMenu.php

<?php
namespace Application\View\Helper\Navigation;

use Zend\View\Helper\Navigation\Menu;

class CustomMenu extends Menu
{
  // override methods as needed
}

CustomPluginManager.php

<?php
namespace Application\View\Helper\Navigation;

use Zend\ServiceManager\ConfigInterface;
use Zend\View\Helper\Navigation\PluginManager;

class CustomPluginManager extends PluginManager
{
    public function __construct(ConfigInterface $configuration = null)
    {
        parent::__construct($configuration);
        $this->invokableClasses[$this->canonicalizeName('menu')]
            = 'Application\View\Helper\Navigation\CustomMenu';
    }

}

menu.phtml

  <?php
            echo $this
                ->navigation('Navigation')
                ->setPluginManager(new \Application\View\Helper\Navigation\CustomPluginManager())
                ->menu();
            ?>

that solution work but I can't accept to construct new object in views for testing matters.

After some research, I found that Navigation Helper is not shared, or it is the twig module that mess up sharing, and if I try to add custom plugin to Navigation (such as a new menu) in module bootstrap, it is just ineffective. But I found an interesting thing in reading Navigation Helper construction in

Zend\Navigation\View\HelperConfig.php

the Navigation plugin manager can be configured in module, global or local config under the key navigation_helpers. That is an easy way to extends Navigation with plugins.

Ex :

module.config.php

'navigation_helpers' => array (
    'invokables' => array(
        'menu' => 'Application\View\Helper\Navigation\Menu',
    ),
),
