Currently we have the following maps available:
Validation: By default, validation option is turned off. Respondents can skip and move ahead in the survey without answering the question. You can enable validation if you don't want to allow respondents to skip this question. By enabling validation option you can see a drop-down with options - force response and request response.
Force response option makes a question mandatory/required, as shown in the above image. The respondents cannot finish survey without answering a mandatory question.
When you select request response, the respondent gets a pop-up in case a question is not answered, requesting to answer the question or continue survey without answering.
