Hi,

I am using jqWidgets tree(using json).If item id and parantId is numeric(like 0,1,2..),it works fine.but my id’s are UUID.
if i use UUID(6682fa5b-2886-4125-a4be-68f3605aaa99 ,6682fa5b-2886-4125-a4be-68f3605aaa92…),i can’t view tree structure.

My Question is how can i use uuid as my tree id instead of numeris ids.
Is it possible?.
can you please help me?

Thanks,

Hello

Here is a working example, based on the demo JSON Tree. Some of the tree items have UUIDs.
