The Interactive Survey mode allows you to automatically move the respondent to the next question once they are done answering a question. When enabled, the survey automatically highlights a single question making it easy for the respondent to answer the survey.
How to enable Interactive mode?
Go to: My Surveys (Select Survey) » Design » Display Settings » Interactive Mode » Enable » Save.
Note: You can enable the back button and exit survey buttons with the Interactive Mode. This will allow respondents to go back and adjust an answer even if they were automatically taken to the next question.
