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.
If you want to hide a field, by default and still function, you can do that by just right clicking on the field and choose "Hide Field"
If you set the "Default Date" to current or with a custom value, then it should still work and will still show the correct date at the back end when the form is submitted.
Do let us know if that works.
