JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I am not sure if I have understood your question correctly. Do you mean to say that you want to allow your users to select more than one option in your form question?
Yes it is possible to achieve your requirement by adding check box question instead of radio button questions. Please be noted that that in radio button questions, user can select only one option but checkox allows you to make multiple selection. Please check the screenshot below:
Hope this helps.
