Menu with subitems didn't show up on Bootstrap5

[numitec]

Hello there,

I installed a vanilla Yii2 advanced template and then follow this guideline: https://www.yiiframework.com/wiki/848/installation-guide-yii-2-advanced-template-with-rbac-system to implement yii2-admin.

But when I try to show the menu, the options with sub items don't show at all: I can only click on the top item.

I instantiate the menu using:

use yii\bootstrap5\Breadcrumbs;
use yii\bootstrap5\Html;
use yii\bootstrap5\Nav;
use yii\bootstrap5\NavBar;

use mdm\admin\components\MenuHelper;

[...]

$menuItems = MenuHelper::getAssignedMenu(Yii::$app->user->id);

		echo Nav::widget([
			'options' => ['class' => 'navbar-nav ml-auto'], // navbar-right'],
			'items' => $menuItems,
			'encodeLabels' => False,
		]);

Any clue?

Thank you!

In order to the reach new requirements present at BS5 (kindly see /yiisoft/yii2-bootstrap5/src/Nav.php):

 * Note: Multilevel dropdowns beyond Level 1 are not supported in Bootstrap 5.

I needed to change the static method normalizeMenu() on the helper: mdmsoft/yii2-admin/components/MenuHelper.php; here it runs with no subitems:

    /**
     * Normalize menu
     * @param  array $assigned
     * @param  array $menus
     * @param  Closure $callback
     * @param  integer $parent
	 * @param  boolean $root
     * @return array
     */
	private static function normalizeMenu( &$assigned, &$menus, $callback, $parent_id = Null, $root = True )
	{
		$children = [];
		$subitem = [];
        $result = [];
        $order = [];
		$item = [];

		// Recorre todas las opciones de menú asignadas al rol
        foreach( $assigned as $id )
		{
            $menu = $menus[$id];

			// Obtiene todas las opciones en el nivel vigente
            if( $menu['parent_id'] == $parent_id )
			{
				// Recupera todos los subitems
				$children = static::normalizeMenu( $assigned, $menus, $callback, $id, False );

				// Procesa los items del nivel vigente y anexa sus subitems
                if( !is_null( $callback ) )
                    $item = call_user_func( $callback, $menu, $root );
                else
				{
					// Only root levels should have items
					if( $root )
					{
						$item = [
							'label' => $menu[ 'name' ],
							'url' => static::parseRoute( $menu['route'] ),
						];

						foreach( $children as $child )
							$item['items'][] = $child;
					}
					else
					{
						if( is_null( $menu['route'] ) )
						{
							$subitem = [
								'<div class="dropdown-divider"></div>',
								'<div class="dropdown-header">'. $menu['name'] . '</div>',
							];

							foreach( $children as $child )
								$subitem[] = $child;
						}
						else
							$item = [
								'label' => $menu[ 'name' ],
								'url' => static::parseRoute( $menu['route'] ),
								'icon' => $menu[ 'icon' ],
							];
					}
				}

				if( count( $item ) )
				{
					$result[] = $item;
					$order[] = $menu['order'];
					$item = [];
				}
				else if( count( $subitem ) )
					$result = array_merge( $result, $subitem );
			}
		}

		if( count( $result ) == count( $order ) )
			array_multisort( $order, $result );

		return $result;
	}

Hope it helps!
