public abstract class Option
extends AbstractComponent

This component serves as a container for one item that is listed as a choice in a Select. A Select offers a selection of choices from which usersu may choose one or more items. The select list is created using a select element which contains a collection of option elements. A string or text describing the item appears between the opening and closing option tags. In order to have a dynamic onpick attribute it is better to use a concrete class of ILinkRenderer with the OptionRenderer.
