php - 子数组集合未与 foreach 一起显示

Question

我有刀片视图，它根据父列表中的选择显示一个列表，就像选择一个类别来显示子类别列表一样。它以前工作得很好，但我突然发现，不是显示子列表，而是显示父列表。

父刀片视图

@endsection

我的控制器

public function categoryList($id=null) {
        $categories_menu = "";
        $categories = Category::with('categories')->where('id',$id)->get();
        $categories = json_decode(json_encode($categories));

        return view('pages.category')->with(compact('categories_menu','categories'));
    }

我不知道可能是什么问题
