Is it possible to pass a value for the dropDownList field?

Question

Yii

I deduce dropDownList, in it the list and the first empty field. Can value be set to a value? It goes empty.
<option value="">Выберите поле</option>

<?= $form->field($model, 'param')->dropDownList(ArrayHelper::map($array,'id','name'), ['prompt' => 'Выберите поле ']);
  ?>

Answer 1

the only way:

$values = ArrayHelper::map($array,'id','name');
$values[<нужное значение>] = 'Выберите поле ';
$form->field($model, 'param')->dropDownList($values);

but it is not absolutely clear - what for to you to set value. What prevents on the server side from simply checking this attribute for empty?
