All Implemented Interfaces:

Serializable, Cloneable, org.zkoss.zk.ui.Component, org.zkoss.zk.ui.ext.AfterCompose, org.zkoss.zk.ui.ext.Scope, org.zkoss.zk.ui.ShadowElement, org.zkoss.zk.ui.ShadowElementCtrl, org.zkoss.zk.ui.sys.ComponentCtrl

public class Choose
extends TemplateBasedShadowElement

The choose tag works like a Java switch statement in that it lets you choose between a number of alternatives. Where the switch statement has case statements, the choose tag has when tags. A a switch statement has default clause to specify a default action and similar way choose has otherwise as default clause.
