public class OptionTag
JSP tag for rendering an HTML 'option
' tag.
Must be used nested inside a SelectTag
.
Provides full support for databinding by marking an
'option
' as 'selected' if the value
matches the value bound to the out SelectTag
.
The value
property is required and corresponds to
the 'value
' attribute of the rendered 'option
'.
An optional label
property can be specified, the
value of which corresponds to inner text of the rendered
'option
' tag. If no label
is specified
then the value
property will be used when rendering
the inner text.
