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 meant for your JotForm account (not for your website), then yes, there's a way to allow other people manage your forms and submissions.
We refer to them as Subusers and you may assign any (or both) of these privileges with them:
1. Edit Forms
2. View Submissions
I'm linking the complete guide below on how to add a Subuser to your account. Keep in mind that your subuser needs his own, separate, JotForm account (a free one would suffice) and the number of Subusers you can add will depend on your current plan (in your case, you're limited to 3 Subusers).
