DevTree, modeled as an IE Behavior, is a feature rich JavaScript tree. With DevTree you can show any kind of hierarchical data very easily with everything being driven by XML. DevTree expects XML both for data, style and layout. DevTree leverages the extensive DHTML DOM using JavaScript to integrate seamlessly with the browser. With over 160 properties, methods and events, you get the same power and features as some of the leading ActiveX tree controls without the need for cumbersome ActiveX downloads and dealing with intricate browser security settings. DevTree alleviates the concern of security conscious and privacy sensitive end users of internet/ intranet applications by working within the browser sandbox unlike ActiveX controls.
