Hi All,
I am just writing this post to help anyone out there who is using JIT Spacetree just like me and facing label overflow issue, where the node is hidden but because of the label it is still visible.
You just need to add overflow: hidden on the #infovis element to hide. I mistakenly remove the css because of which it started showing and after a while only I had this overflow issue. So just do this and your issue will be solved.
Cheers!
