JavaScript: lz.opttree

extends <view> » <node> » lz.Eventable »

A keyboard navigable (with arrow keys) tree control that supports selection and dynamic data loading. This tree must be backed by an XML DOM datastructure and presented within a clipping region. The datapath for an opttree must resolve to a single LzDataElement which is the undisplayed root of the tree.
