Question

How to make a dropdown in yii2 using an activeform and a model? Since all the methods has changed in yii2,how it is done

Answer 1

It seems you've found your answer already but since you mentioned the active form I'll contribute with one more, even if it differs only ever so slightly.

field($model, 'attribute')
        ->dropDownList(
            $items,           // Flat array ('id'=>'label')
            ['prompt'=>'']    // options
        );

    ActiveForm::end();
?>
