Activate multiple selection on choice questions
Go to your quiz and click on the question where you want to activate the multiple selection.
This can be done in the Question Settings (click on the wrench icon). This should open a sidebar with the question options.
Then activate the “Multiple Selection” toggle.
Optionally, in the “Range” values you can set the minimum and maximum number of choices that your customer can select.
Warning! If you allow Multiple Selection on a question, do not exclude products or collections in the choices. Products may be mutually excluded and you’ll end up with empty quiz results.
Note: If you make a Multiple Choice question Optional, you won’t be able to select a Range.
