原先的权限把控：必须把‘items'下的权限‘visible'都加进‘数据维护’下面去
[ 'label' => '<i class="fa fa-edit"></i><span class="nav-label">数据维护</span>',
'visible' => Yii::$app->user->can('product-category/list') || Yii::$app->user->can('region/list'), 'items' => [ [ 'label' => '产品分类管理', 'url' => ['product-category/list'], //'visible' => Yii::$app->user->isGuest ], [ 'label' => '产品管理', 'url' => '#', //'visible' => Yii::$app->user->isGuest 'visible' => Yii::$app->user->can('product-category/list'), ], [ 'label' => '地区管理', 'url' => ['region/list'], //'visible' => Yii::$app->user->isGuest ], ], ],
然后权限把控在组件中
