When creating a questionnaire it is possible to manage conditions and therefore, depending on the answer, ask or simply show a notice.
Example ANAC site when asked if you want to provide your identity or not.

Thank you



Dear Roberto,

Already exists the possibility to attach select box options to new questions to be triggered conditionally (trigger feature) but there are currently no questions that acts simply as a ‘notice text’.

We understand your need and we will open a ticket on our github in order to add this requirement to our roadmap.

Thank you for the feedback.
