public class UISelectItem
extends UIComponentBase
```
UISelectItem is a component that may be nested inside a UISelectMany or UISelectOne component, and causes the addition of a SelectItem instance to the list of available options for the parent component. The contents of the SelectItem can be specified in one of the following ways:
- The value attribute's value is an instance of SelectItem.
- The associated ValueExpression points at a model data item of type SelectItem.
- A new SelectItem instance is synthesized from the values of the itemDescription, itemDisabled, itemLabel, itemEscaped, and itemValue attributes.
