Yii2 dropDownList Default value

Question

In yii2 I have a dropdownlist:

<?= $form->field($model, 'Körperschaft')->dropDownList(['a' => 'Item A', 'b' => 'Item B', 'c' => 'Item C'])?>

How can I set 'Item B' as a default value?

Answer 1

I got it! The solutions is to write in the controller:

public function actionCreate()
{


    $model->Körperschaft='b';
