Advanced processing of XML allows dhtmlxTree 1.1 to handle large amounts of data. Dynamical loading of items from XML stream gives a possibility to create trees with unlimited number of nodes.
dhtmlxTree 1.1 has drag-and-drop functionality (within one tree, between trees, between frames). Drop-as-sibling behavior makes it easy to reorder nodes in a tree view.
Other notable feature enhancement in this version is built-in context menu (right click) enabling web developers to create user-friendly navigation interface by putting most necessary commands inside this menu and attaching it to the whole tree, group of items or individual item.
dhtmlxTree 1.1 has checkbox system in order to use this component as a navigation bar with selection lists. Besides usual two-state checkboxes (checked item, unchecked item), there is a possibility to use three state checkboxes with “partly-checked” value (some sub-items are checked).
Version 1.1 also introduces possibility to use multi-line tree items, build a tree without items and find necessary node by its mask.
