DropdownList about yii2-multiple-input

[unclead]

Не понял вопроса 😄

Вот пример из документации

'columns' => [
        [
            'name'  => 'user_id',
            'type'  => MultipleInputColumn::TYPE_DROPDOWN,
            'enableError' => true,
            'title' => 'User',
            'defaultValue' => 33,
            /* it can be an anonymous function
            'items' => function($data) {
                return [
                    31 => 'item 31',
                    32 => 'item 32',
                    33 => 'item 33',
                    34 => 'item 34',
                    35 => 'item 35',
                    36 => 'item 36',
                ];
            }
            */
            'items' =>  [
                31 => 'item 31',
                32 => 'item 32',
                33 => 'item 33',
                34 => 'item 34',
                35 => 'item 35',
                36 => 'item 36',
            ]
        ],
