QS:Time limit
From LimeSurvey Manual
Time limit (time_limit)
Description
Setting the time_limit attribute on a question will cause a countdown timer to begin counting down as soon as that question/page is loaded. At the expiry of the countdown timer the question will either automatically move on to the next page or become read-only.
The timer attributes work best with surveys using the Question by question format. They can also be used in the surveys that use the Group by group format. But, running the group by group format can break the mandatory questions, and implicitly, the survey.
Valid values
- Any positive integer number
Example
Set it to 240 to count down from 4 minutes (240 seconds).
