Answer 1

我终于找到了这个问题。
我需要定义与该领域合作的Ajax路线，要么创建自己的端poin，要么使用fetchoperation https://backpackforlaravel.com/docs/5.x/crud-operation-fetch#about-1 。

在QuestionCrudController中：

    use \Backpack\CRUD\app\Http\Controllers\Operations\FetchOperation;
...

    public function fetchTags()
    {
       return $this->fetch(Tag::class);
    }
