Use the same values ​​for key and value

in this sampling country there is a code and a name, and mao gives you key value

  $listData=ArrayHelper::map($countries,'code','name'); 

in this example

  $listData=ArrayHelper::map($countries,'name','name'); 

enter value, value

 echo $form->field($model, 'name')->dropDownList($listData, ['prompt'=>'Choose...']);
