public class ELOptionsCollectionTag
extends org.apache.struts.taglib.html.OptionsCollectionTag

Tag for creating multiple <select> options from a collection. The collection may be part of the enclosing form, or may be independent of the form. Each element of the collection must expose a 'label' and a 'value', the property names of which are configurable by attributes of this tag.

The collection may be an array of objects, a Collection, an Enumeration, an Iterator, or a Map.

NOTE - This tag requires a Java2 (JDK 1.2 or later) platform.

This class is a subclass of the class org.apache.struts.taglib.html.OptionsCollectionTag which provides most of the described functionality. This subclass allows all attribute values to be specified as expressions utilizing the JavaServer Pages Standard Library expression language.
