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.
You do not have to explicitly change the height of the form. The builder is designed in such a way that you keep adding the question and the form height will keep increasing automatically.
Do get back to us if you meant to as something else.
Thanks for sharing the URL of the website where your form is embedded. We now understand the issue is when embedding your form to your web page and not in our form builder.
So, the issue happens because the height of the iframe is not long enough to display all the fields, you have to increase its height to 2200px at least while getting the iframe code:
Please note that it is necessary to manually change the height of the iframe because it provides a fixed height and will not adjust automatically. For that purpose you may use the Embed Code, but some times it may allow script conflicts as the scripts of your form are expossed.
Please inform us if you need further assistance with this query.
