Well after month of silent (7 I think) I got back with a new post on Jquery TreeView.
First you can download the plugin from here. I must say this plugin is amazing very fast even with large trees.
The problem of Jquery TreeView is the lack of RTL (Right To Left) support for languages like: Hebrew, Arabic etc…
If you got the same problem I have and you need Jquery TreeView RTL version you can download it from my blog right here.
To the AJAX fans I also add a nice cool ajax application example you can download it from here.
Hope it helps
