Display parent folder and sub folder through expand and collapse (like accordian)

Hi

I am trying to implement parent folder and subfolder : Site 1: Parent folder1 ( expanded view ) Child Folder1 --> Documents Child Folder2 --> Documents Parent folder2 Child Folder1 --> Documents Child Folder2 --> Documents Child Folder1 --> Documents Site 1: Parent folder1 Parent folder2

I was looking through the blogs and found somewhat similar code :pastebin.com/my4umDdm .The issue is i am having a webservice call to get the folder structure .

Can anyone provide a solution to this ?
