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, it is not quite possible, the form needs to be connected on the internet for its scripts and other functionality to work. This includes widget, apps, scripts and other resources. Without internet connection, they won't function.
The current solution that we have for offline data collection is by converting the form to a fillable PDF form. You can save the progress on the fillable PDF form as a local file AND submit it online whenever there's an available internet connection.
You can check our guide about the fillable PDF feature on this link: https://www.jotform.com/help/312-Fillable-PDF-Everything-you-need-to-know-about-JotForm-Fillable-PDF-Creator
Our founder also has a blog post about it here: https://www.jotform.com/blog/193-How-to-Create-a-Fillable-PDF-Form-using-JotForm
I hope that helps.
