public class CmsSelectComboBox
extends com.google.gwt.user.client.ui.Composite
implements I_CmsFormWidget, I_CmsHasInit, com.google.gwt.event.logical.shared.HasValueChangeHandlers<String>, I_CmsHasGhostValue
Hybrid select / combo box widget.
This widget behaves like a select box, until a button on it is pressed, after which the select box is transformed into a combo box. The reason for this is that the combo box always displays the currently selected value itself, rather than the label from the widget configuration, which may be confusing to nontechnical users in some cases.
