What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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 you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
To adjust the width of the phone number field, you can add this CSS to your form:
width : 130px;
That should be slim enough to remain on the same line as your other fields but wide enough to show the full input.
If you have any further questions, let us know and we will be happy to help.
