Best open-source javascript tree?

Question

Could you propose open source, but commercial-friendly licensed (non-GPL) Javascript trees?

Please take into account that I need it for an existing Web application, so I am not sure whether other tools such as GWT or Echo would be appropriate.

I have already checked:

• Dojo Tree
• jQuery.Dynatree.js (JQuery)
• JSTree (JQuery)
• Mif.Tree (Mootools)
• YUI Tree (Yahoo User Interface)

I have ruled out DHTMLX and ExtJS (both GPL, they require the whole project to be GPLed).

Thanks in advance for your suggestions!

UPDATE: This question is old, the above list should no longer be taken into account. I'm sure there are more and better alternatives now.

Answer 1

jsTree seems best.

• Open source: MIT license
• Features: lazy loading, context-menu, keyboard navigation, drag & drop, inline editing, customizable, CDN hosted.
• Stackoverflow has 1,551 questions tagged with jsTree
• Alexa page rank of jstree.com is better than others

Other close contenders:

1. Fancytree (upgraded version of Dynatree)
2. zTree
