With CaptainForm WordPress Form Builder Plugin you can set the amount of time respondents have for filling out the WordPress quiz, by adding a countdown timer to it. If the respondent hasn’t submitted the quiz when the time is up it will be submitted automatically.
To activate the countdown timer to your WordPress quiz, just go to the Settings → Advanced section of your form and under Quiz tick the Show countdown timer option. This will lead to a dropdown area with a box and a dropdown list.
In the dropdown list, you can choose the WordPress quiz to count the time in seconds, minutes or hours. In the box on the left, you should add the exact amount of time you want the countdown timer to be set. Hit Save changes on top and you are done.
Note: You cannot set two base units for the countdown timer.
That’s it! From now on, form users will see a countdown timer on the top right corner of the quiz. Once the time has finished, the quiz will be automatically submitted.
