Sådan benyttes komponenten Option klassen
Først skal du inkludere den fil der beskriver komponenten, som en klasse fil
<? require_once(HTML_PACKAGE_PATH.'/Option.php'); ?>
Dernæst kan du enten benytte komponenten som et taglib (statiske metoder):
<? Option::display($param1, $param2, $param3, ...); ?>
eller du kan lave en instance af komponenten og benytte metoderne direkte:
<? $object = new Option($param1, $param2, $param3, ...); print $object->getHtml(); ?>
Sådan vises komponenten Option klassen
