如何将颤振api json数据实现为第三级类别的列表视图？

Question

我正在尝试开发一个颤振应用程序，这个想法是：

医院和医院的doctors.

• Doctors有很多

1. 列表，按部门分类，例如:心内科，神经科。

。

这样做的目的是从api json数据中获得医院列表，单击特定医院后，应该有部门列表(api json data )，然后从列表中选择一个特定的部门--它将加载来自该部门的列表中的所有医生。

有人能帮忙吗？我用Laravel 9作为后端。

- Json code
    
    {
        "hospital":[
           {
            "name": "hospital1",

                {
                    "name": "department1",
