Among the new features found in dhtmlxTree version 1.3 are:
- Editable tree nodes. User double-clicks on a tree node and a text box appears allowing to edit text or enter new text for the node.
- Automatic update of server side data source. All changes performed on the tree in web browser can be automatically saved in backend database on server side. This became possible because of new advanced mechanism which provides the ability to pass updates of tree view (whether node text or tree structure was changed) to the server side and save them in appropriate form in database.
- Distributed Parsing to work with tree levels which contain a large number of nodes. This feature provides the possibility to dynamically parse tree levels with hundreds of nodes. When user clicks on tree node to collapse the branch with large amount of children, only first twenty subnodes are displayed initially. Then others are dynamically processed and displayed by the same portions on demand.
- Keyboard support. It lets users intuitively expand/collapse tree nodes, navigate inside tree view, add/delete nodes, and more.
- Extended drag-and-drop functionality. The major enhancements include the ability to select and drag multiple tree items, support for drag-and-drop between frames/iframes, and customizable drag-and-drop between dhtmlxTree and dhtmlxGrid.
- RTL (Right-to-Left) language support (Arabic, Hebrew, etc.). Language configuration can be easily switched from RTL to LTR and vice versa.
Furthermore, dhtmlxTree v1.3 supports custom sorting of tree nodes and extended serialization to XML. All these new additions and improvements offer increased versatility and flexibility of the tree menu and allow the control to meet the most complex developer’s needs.
