Try like this

   <?php
     use yii\helpers\ArrayHelper;
     use app\models\Product;
    ?>

   <?= $form->field($model, 'parent_id')->dropDownList(
        ArrayHelper::map(Product::find()->all(),'id','name'),
        ['prompt'=>'Select ']) 
    ?>

You are trying to echo an array, change <?= to <?php in:

<?= $listdata=ArrayHelper::map(Product::find()->all(),'id','name'); ?>
