QuestionPro provides the feature to change the answer type and layout after the question and answers are added.
For example: If you have added a radio button question in the survey, but now you want to change it to a checkbox question, instead of deleting the question and re-adding it, you can directly change the question and answer type in the question settings section.
To change the answer type, go to: Survey » Workspace » Settings.
Select the answer type.
