我试图解决这个问题一段时间，但我无法找到一个令人满意的方式来得到我想要的。也许这很简单，但我太没经验了。

我需要一种方法来显示给定类别的子类别的所有文章标题，如下所示：

Category "x"
  Subcategory 1xa
    Post 1xa
    Post 2xa
  Subcategory 2xb
    Post 1xb
    Post 2xb
Category "y"
  Subcategory 1ya
    Post 1ya
    Post 2ya
  Subcategory 2ab
    Post 1yb
    Post 2yb
etc

我真的不能用我有限的知识来做这件事。我所能得到的只是子类别列表（没有帖子标题）或每个类别、子类别和帖子的列表。我想让每个类别、子类别和帖子都在它们下面（未分类的除外），就像上面的顺序一样。我看到了很多帖子，但没有找到解决方案，因为我不擅长编码。

谁能帮我一下吗？提前非常感谢！
