Note that this tag specifically does not support the
styleId
tag attribute, which causes the HTML
id
attribute to be emitted. This is because the HTML
specification states that all "id" attributes in a document have to be
unique. This tag will likely generate more than one option
element element, but it cannot use the same id
value. It's
conceivable some sort of mechanism to supply an array of id
values could be devised, but that doesn't seem to be worth the trouble.
Parameters: sb StringBuffer accumulating our results value Value to be returned to the server for this option label Value to be shown to the user for this option matched Should this value be marked as selected?
