Often there is a need to show a hierarchically structured data.
Our dhtmlxTree (DHTML extensions Tree) lets you do this in an easy and most comfortable way - in any browser! This JavaScript Tree Menu component allows creating user-friendly navigation bar for a commercial application or a web site. Menu items are organized into compact, hierarchical tree structure so users can find information they need easily.
Having such feature, as dynamical loading of items from XML stream allows dhtmlxTree to handle large amounts of data. Drag-and-drop makes it possible to drag items not just within one tree, but between different trees. Try by yourself now:

 
Drag & drop items within the trees as well as between trees
Double-click on folder label or click on [+] plus to expand subitems.


Rich client-side Javascript API gives an opportunity to change tree styles (folder images, fonts, indents, and colors) and manage any part or activity. Our DHTML tree works perfectly in all main Web-browsers for Windows, Mac OS X, Linux or Unix so you don't have to care about the browser compatibility.
dhtmlxTree has built-in checkboxes providing a handy tool for any kind of navigation system where selection lists are required.
