If the tree has hundreds of nodes, subnodes can be asynchronously loaded on the client side and then displayed by portions on demand. It's possible due to Distributed Parsing functionality implemented in dhtmlxTree. Smart Rendering is another feature that solves performance problems in trees with great number of nodes per level.
Extended drag-and-drop functionality greatly simplifies tree usage. Drop-as-sibling behavior makes it easy to reorder nodes in a tree view. The tree control supports drag-and-drop not only within one tree, but between trees, even if they are located in different frames or iframes. You also can select and drag multiple tree items.
This DHTML tree has checkbox system in order to use this component as a navigation bar with selection lists. In addition to usual two-state checkboxes (checked item, unchecked item), you can use three state checkboxes with "partly-checked" value (some sub-items are checked).
dhtmlxTree is distributed under both GNU GPL and commercial license (PRO edition). Source code is available.
