Customizing the menu

How to customize the sidebar menu

Decorate the sidebar menu

To customize the admin menu, you need to decorate the sylius_admin_ui.knp.menu_builder service.

declare(strict_types=1);

namespace App\Menu;

use Knp\Menu\FactoryInterface;
use Knp\Menu\ItemInterface;
use Sylius\AdminUi\Knp\Menu\MenuBuilderInterface;
use Symfony\Component\DependencyInjection\Attribute\AsDecorator;

#[AsDecorator(decorates: 'sylius_admin_ui.knp.menu_builder')]
final readonly class MenuBuilder implements MenuBuilderInterface
{
    public function __construct(
        private readonly MenuBuilderInterface $menuBuilder,
    ) {
    }

    public function createMenu(array $options): ItemInterface
    {
        $menu = $this->menuBuilder->createMenu($options);

        $menu
            ->addChild('dashboard', [
                'route' => 'sylius_admin_ui_dashboard',
            ])
            ->setLabel('sylius.ui.dashboard')
            ->setLabelAttribute('icon', 'tabler:dashboard')
        ;

        return $menu;
    }
}

Add submenu items

Now you can add submenu items:

// ...
#[AsDecorator(decorates: 'sylius_admin_ui.knp.menu_builder')]
final readonly class MenuBuilder implements MenuBuilderInterface
{
    // ...
    
    public function createMenu(array $options): ItemInterface
    {
        $menu = $this->menuBuilder->createMenu($options);
        // ...
        $this->addLibrarySubMenu($menu);

        return $menu;
    }
    
    private function addLibrarySubMenu(ItemInterface $menu): void
    {
        $library = $menu
            ->addChild('library')
            ->setLabel('app.ui.library')
            ->setLabelAttribute('icon', 'tabler:books')
        ;

        $library->addChild('books', ['route' => 'app_admin_book_index'])
            ->setLabel('app.ui.books')
            ->setLabelAttribute('icon', 'book')
        ;
    }
}

🧠 Collapse your custom menu by default

It's possible to expand your parent menu category on page load by default. For that, you have to set the setExtra attribute like this:

$library = $menu
    ->addChild('library')
    ->setLabel('app.ui.library')
    ->setLabelAttribute('icon', 'tabler:books')
    ->setExtra('always_open', true);

However, ensure that you set the attribute in the parent menu, not in one of the child menu items.
