At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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 I understood right your question you wish to have more than 1 field per line.
To achieve that you can click on the field and select "shrink".
You can do this to all the fields you wish and then you can just drag them into the same line.
Please let us know if it worked out as wished.
