dhtmlxTree

dhtmlxTree (DHTML extensions Tree) is a feature rich JavaScript tree menu that allows you to effortlessly create attractive and fast-loading hierarchical interfaces with cross-browser compatibility, AJAX support, in-line node editing and drag-n-drop capabilities. Rich client-side API provides complete control over the tree appearance and behaviour. Special techniques implemented into component allow loading really big trees in moments.

The tree implements AJAX model of data processing which allows the tree content to be updated seamlessly without reloading the entire webpage. All changes performed in the tree on the client-side can be automatically saved to the database in real time.

Advanced drag-and-drop makes it possible to drag items not just within one tree, but between different ones (even if trees are located in different frames or iframes).
