Exactly like smanek described to define the tags. Then you use them like this: <question:required> <question:text> Would you recommend us to a friend? </question:text> <answer:choice> <input type="radio" value="Yes"> </answer:choice> <answer:trigger> <input type="radio" value="No"> </answer:trigger> <question:subquestion question:trigger="No"> Please explain why you wouldn't recommend us: ... </question:subquestion> </question:required> I then used jQuery to bind events to the newly created tags to hide/display subquestions based on the response, and css to style it.
