public class UISelectItems extends UIComponentBase
UISelectItems is a component that may be nested inside a
UISelectManyorUISelectOnecomponent, and causes the addition of one or moreSelectIteminstances to the list of available options in the parent component. Thevalueof this component (set either directly, or acquired indirectly aValueExpression, can be of any of the following types:- Single instance of
SelectItem- This instance is added to the set of available options for the parent tag. - Array of
SelectItem- This set of instances is added to the set of available options for the parent component, in ascending subscript order. - Collection of
SelectItem- This set of instances is added to the set of available options for the parent component, in the order provided by an iterator over them. - Map - The keys of this object (once converted to Strings) are assumed to be labels, and the values of
this object (once converted to Strings) are assumed to be values, of
SelectIteminstances that will be constructed dynamically and added to the set of available options for the parent component, in the order provided by an iterator over the keys.
