AJAX Multilevel Javascript/DHTML Tree

Veerendra Shivhare pointed us to a multilevel AJAX tree that he use to explore the Amazon Catalogue Tree. Amazon tree allow you to naviguate throw different amazon categories marked with green dots, once you reach an item marked with red dots you can retrieve the item details such price, image, rating, reviews ...

The most interesting thing is that you can have different action for each level, and different kind of items in each level too. Which bring more flexibility and what I found more interesting is that result are cached so there is no need to load data again if you close the tree and open it again. I think this will solve many problems for people having large data that they need load using dhtml tree. The script is a modified version of JSCookTree and using PHP for the server side scripts.

It's been mentioned on this blog before, back in August, but another component that has similar functionality is LiveTree. It's under continuous development and evolving new features, open-source, well documented, and has lots of examples. You can get it here: http://www.epiphyte.ca/code/live_tree.html

Full disclosure: I'm the creator of this component.
