How can I get the form to fit the page?

How can I get the form to fit the page. It wont fit to the page or give me the option to select fullscreen mode?

Is this form embedded on a webpage? Please provide the URL of the webpage where the form is embedded so that we can check the issue.

Normally, if you embed the form to a webpage, the width of the form will depend on the container element where you will add the code.

We will wait for your reply. Thank you.
