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 understand that you want to have 3 columns on your JotForm. You can arrange the fields in columns by enabling Form columns option from the Form Designer.
It is also required to use the field positioning to shrink the fields as required.
Hope this information helps. If you are referring to something different, please provide us with more information on your requirement so that we can guide you in the right direction.
