Question

Yii

in the admin panel I write a widget for lists of categories and then an error occurs when I write this
<?= \app\components\MenuWidget::widget(['tpl' => 'select', 'model' => $model])?>
displays error Setting unknown property: app\components\MenuWidget::model

Answer 1

you probably just don't have the $mode property defined
