            return $this->render('depdrop', [
                'model' => $model,
            ]);
        }
    }

public function actionDepdrop()

{

$model = new \backend\models\Departments();

if ($model->load(Yii::$app->request->post())) {

$model->department_created_date = date('Y-m-d h:m:s');

use kartik\select2\Select2;
use yii\helpers\Url;

use kartik\depdrop\DepDrop;

use kartik\select2\Select2;

use yii\helpers\Url;
