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.
Unfortunately radio buttons wont allow multiple answers. Check boxes are the best choice for what you are trying to achieve as they do allow for multiple answers.
Kindly let us know if you need additional support. Thank you.
