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.
I have checked your webpage and your form is loading fast on my end. Form collapse widgets are loaded in less then one second.
Maybe this is related to your internet connection. Can you please try to test your webpage from some other location or from some other device.
You can also try to change embedded form URL from https://form to https://www to see if that will resolve your issue.
Hope this will help. Let us know if you need further assistance.
