+Create Menu Event & Event Listener
+---
+#### Step 1: Create Menu
+You must register the menu as a service for the menu activity.
+
+```php
+<?php
+// src/Menu/FirstMenu.php
+
+namespace App\Menu;
+
+use Pd\MenuBundle\Builder\ItemInterface;
+use Pd\MenuBundle\Builder\Menu;
+use Pd\MenuBundle\Event\PdMenuEvent;
+use Symfony\Component\DependencyInjection\ContainerInterface;
+
+class FirstMenu extends Menu
+{
+    /**
+     * @var EventDispatcherInterface
+     */
+    private $eventDispatcher;
+
+    /**
+     * MainNav constructor.
+     * @param EventDispatcherInterface $eventDispatcher
+     */
+    public function __construct(EventDispatcherInterface $eventDispatcher)
+    {
+        $this->eventDispatcher = $eventDispatcher;
+    }
+
+    /**
+     * Override 
+     */
+    public function createMenu(array $options = []): ItemInterface
+    {
+        //...
+
+        /*
+         * Create Event
+         */
+        $this->eventDispatcher->dispatch(
+            'custom.menu.event',
+            new PdMenuEvent($menu)
+        );
+
+        return $menu;
+    }
+}
+```
+#### Step 2: Create Menu Listener
+Now let's create a listener for the event.
+```php
+<?php
+// src/Listener/MenuListener.php
+
+namespace App\Listener;
+
+use Pd\MenuBundle\Event\PdMenuEvent;
+
+class MenuListener
+{
+    public function onCreate(PdMenuEvent $event)
+    {
+        // Get Menu Items
+        $menu = $event->getMenu();
+
+        // Add New Item
+        $menu->addChild('demo_item', 5)
+            ->setLabel('Home Page')
+            ->setRoute('home_route');
+    }
+}
+```
+Let's create a service for the listener.
+```yaml
+    App\Menu\MenuListener:
+        tags:
+            - { name: kernel.event_listener, event: custom.menu.event, method: onCreate }
+```
