如何在Xamarin Forms中的另一个列表中获取列表并将其绑定到ListView中？

Question

I want to show one list which is inside of another list in Xamarin.Forms. I have JSON structured like the following:

 [
   {
     "CategoryName": "Tea",
      "SubCategories" :
      [
       {
       "SubCategoryName": "GreenTea",
       }
      ] 
   }
 ] 

My JSON looks like this. I am able to bind outer list which is CategoryName list to list view but now I want to show SubCategoryName under CategoryName . I am using expandable view here.

Can anyone tell me how can I achieve this?

You can use ListView Grouping, there are many tutorials how to do it, like this article , or this code preview . James Montemagno did a great article too
