添加新的列表选项，动态刷新更新后的列表

我正在通过尝试使用它制作一个项目来学习Yii2。

我有一个表格，里面有一些列表。我想实现一个添加新的列表选项的功能。

当前点击"添加新选项"按钮调用弹出式表单。提交后，Yii带我到这个新选项的页面。原因:

public function actionCreate()
{
    $model = new Request();
    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        return $this->redirect(['view', 'id' => $model->id]);
    } else {
        return $this->render('create', [
            'model' => $model,
            'manager' => Stuff::find()->all(),
            'movercompany' => MoverCompany::find()->all(),
            'worktype' => Worktype::find()->all(),
            'customer' => Customer::find()->all(),
        ]);
    }
}

提交后我想要的只是刷新更新的列表并选择新的选项。

我该怎么做?
