Powerful drag-and-drop capabilities allow you to drag the tree items not just within one tree, but between different trees (even if they are located in different frames or iframes). You can try this functionality right now:
Rich client-side API provides complete control over the treeview appearance and behavior. In addition to the functional API, dhtmlxTree also provides an object constructor that allows you to define object properties within a single command.
To simplify server-side integration, we've developed the dhtmlxConnector library that provides client-server data communication (available for PHP, Java, ASP.NET, and ColdFusion). You can also use dhtmlxTree with the custom server-side code.
Once built into your web site or application, dhtmlxTree provides a high-performance navigation system. Smart Rendering brings excellent performance for trees with a great number of nodes per level.
With Distributed Parsing, tree levels are loaded asynchronously: when the node is open, only the first portion of sub-nodes is displayed, then other nodes are dynamically processed and displayed by the same portions on demand.
Note that some features are available in the PRO Edition only.
dhtmlxTree is available in Standard and PRO Editions (feature comparison table).
