@Raoul,
Thanks, vraag hoe ziet dan je Class eruit?
Thanks, vraag hoe ziet dan je Class eruit?
Iedere form element heeft een render method, omdat natuurlijk iedere method een andere HTML geeft. In de render method dan, in de form class, dan stop ik iedere render van iedere element in een variable en return ik die.
