What is Survey response type Multi-Answer?
After your one click embedded question you can add follow-up questions on landing pages.
For these you have a full range of Response Types to select from including Multi-Answer.
The Multi-Answer feature allows the survey recipient to select responses from a list.
These responses automatically update the Survey activity page.
(Responses can’t be mapped to a custom field in the contact profile in the same way as a multiple choice text or number response).
