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, you can't add a File Upload field in the Configurable List widget. However, you can align the form fields in 2 columns by using the "Shrink" function. You just need to right click the field and then select the "Shrink" option.
