Related to my How do I create a custom post type for a training CMS in WordPress? question, if I have a custom page type created for the presentation of training content, how could I include active content, such as a multiple choice test in some of these training pages? would very much prefer that the training page (i.e. my custom post type) is aware of the test, and acts as a micro-LMS, handling navigation back and forth between questions etc. It would break my cold, hard heart to simply plug the test into an iframe, so what else can I do?
