Add Menu

Add an admin Menu entry for a Sylius Resource

Ask the user for the ModelName if not provided. Ask also:

• Submenu label key — the group's identifier when the plugin ships several related resources under one parent. Default: {model_snake_plural} (works when there's only one resource).
• Submenu icon — Tabler icon name. Optional.
• Item icon — Tabler icon name.

Prerequisite: admin routes exist (/sylius-plugin:add-routes).

Sylius admin menu customization is done via an event listener on sylius.menu.admin.main (the left sidebar) — this is the idiomatic approach per the Sylius customizing-menus guide.

1. Create or extend the AdminMenuListener

One listener per project, not one per model. If src/Menu/AdminMenuListener.php already exists, append a new addChild() call under the right submenu — don't create a new listener class.

src/Menu/AdminMenuListener.php:

<?php

declare(strict_types=1);

namespace $SYLIUS_NAMESPACE\Menu;

use Sylius\Bundle\UiBundle\Menu\Event\MenuBuilderEvent;

final class AdminMenuListener
{
    public function __invoke(MenuBuilderEvent $event): void
    {
        $menu = $event->getMenu();

        $submenu = $menu
            ->addChild('{submenu_key}')
            ->setLabel('${SYLIUS_PREFIX}.ui.{submenu_key}')
            ->setLabelAttribute('icon', '{submenu_icon}')   // remove this line if no icon
        ;

        $submenu
            ->addChild('${SYLIUS_PREFIX}_admin_{model_snake}_index', [
                'route' => '${SYLIUS_PREFIX}_admin_{model_snake}_index',
            ])
            ->setLabel('${SYLIUS_PREFIX}.ui.{model_snake_plural}')
            ->setLabelAttribute('icon', '{item_icon}')
        ;
    }
}

When extending: keep the $submenu = $menu->addChild('{submenu_key}')... block once, then append extra $submenu->addChild(...) blocks — each resource becomes a new item under the same submenu.

2. Register the listener

Add to config/services.yaml:

services:
    ${SYLIUS_PREFIX}.listener.admin.menu:
        class: $SYLIUS_NAMESPACE\Menu\AdminMenuListener
        tags:
            - { name: kernel.event_listener, event: sylius.menu.admin.main }

The listener is invokable (__invoke), so no method: attribute is needed on the tag.

3. Add translations

Get the project's default locale:

vendor/bin/console debug:container --parameter=kernel.default_locale

Add to translations/messages.{locale}.yaml:

${SYLIUS_PREFIX}:
    ui:
        {submenu_key}: '{Submenu label}'
        {model_snake}: '{ModelName}'                        # singular — Sylius auto-uses it for create/show titles
        {model_snake_plural}: '{ModelName}s'                 # plural — Sylius auto-uses it for breadcrumbs
        manage_{model_snake_plural}: 'Manage {ModelName}s'   # subheader (also used by /sylius-plugin:add-routes)

The singular ${SYLIUS_PREFIX}.ui.{model_snake} is auto-resolved by Sylius's admin templates for titles like "New {ModelName}". Must stay a scalar — never nest anything under it.

4. Clear cache

vendor/bin/console cache:clear

5. Verify

• vendor/bin/console debug:event-dispatcher sylius.menu.admin.main lists $SYLIUS_NAMESPACE\Menu\AdminMenuListener among the registered listeners
• vendor/bin/console debug:router ${SYLIUS_PREFIX}_admin_{model_snake}_index resolves the target route
• vendor/bin/console debug:translation {locale} --domain=messages 2>&1 | grep '${SYLIUS_PREFIX}.ui.' lists every ui key you added.
