Examples of org.openfaces.component.select.TwoListSelection

org.openfaces.component.select.TwoListSelection
The TwoListSelection component provides an alternative interface for selecting a list of items. It displays two lists of data and allows the user moving items between them thus constructing a list of selected items in one of them. As opposed to the ordinary selection components such as the standard HtmlSelectManyListbox it also allows the user to reorder the selected items. @author Kharchenko
