Set Dropdown list width in yii2

You can just add style in dropDownList show below code

'style' => 'width:90px !important'

<?= $form->field($model, 'experience_month')->dropDownList([ '0' => 0,'1'=>1,'2'=>2,'3'=>3,'4'=>4,'5'=>5 ,'6'=>6,'7'=>7,'8'=>8,'9'=>9,'10'=>10,'11'=>11], 

['style' => 'width:90px !important', 'prompt' => 'Month'])->label('Year & Month') ?>

Yii2 Display DropDownList Values Using funtion

make a function in your model to return an array of your list

public function getOptions()
{
   return array(
      'EASY',
      'MEDIUM',
      'HARD',
   );
}

then you could use it like this

echo $form->dropdownList($model , 'category' , $model->options); // this will use that function to get the array

yii2:drop-down list for multiple values concat in one line

use this code concat multiple fields in single line.

ArrayHelper::map(\app\models\Medicine::find()->asArray()->all(),
    'id',
    function($model, $defaultValue) {
        return $model['medicine_name'].'-'.$model['medicine_id'];
    }
)

Example

<?= $form->field($modelSalesitem, "[{$i}]stockitem_id")
                                    ->dropDownList(
                                    ArrayHelper::map(Stockcenter::find()->where(['center_ccid'=>1])->all(),       
                                    'stockitem_id' ,  function($model, $defaultValue) {
                                                    return $model['stockitem']['item_name'].'    -'.$model['stock'].'  -                                                     -'.$model['amount'];}),
