When I have a rather long mandatory array question, I would like to add some "do not answer this question" to ensure that participants really read questions (e.g. to eliminate people who answer people who are just bored and click the same answer everywhere).

The idea is to still have a mandatory question (with block of the validation and red items when you miss one) without a "No answer" option.

The only workaround I've found was something about making one "No answer" option, hiding it with CSS/JS and check this option with JS for the "do not answer" question. Seems to be a complex :/
