All Implemented Interfaces:

java.io.Serializable

public class SelectItemGroup
extends SelectItem

SelectItemGroup is a subclass of SelectItem that identifies a set of options that will be made available as a subordinate "submenu" or "options list", depending upon the requirements of the UISelectMany or UISelectOne renderer that is actually used. In general, the value property of this instance will be ignored, and the label property of this instance will be used to label the submenu.

Although it is feasible to incorporate SelectItemGroup instances in he selectItems property of this instance (thereby creating a data structure suitable for cascading submenus), some renderers may place restrictions on the level of nesting they support. For example, HTML based renderers that create an <select> element will typically render this instance as an <optgroup> element, but the HTML 4.01 Specification disallows nested option groups.
