I want to add smileys below the numbers in the NPS question. Is that possible? If so, how should I go about it?
There is not a built in option for adding icons below the numbers/answer options in a question. SurveyGizmo does have some documented CSS for changing the icons themselves:
Though I probably would not recommend this for an NPS question as that question type is intended to have respondents rate on a 10 point scale..
