I am trying to embed a form with using the source code option.

I am trying to embed a form with using the source code option.

But when I submit the form thank you page is not coming to the same page. Is it possible for us to just refresh where the form is coming in.

I mean when we use it as Iframe it reloads that portions of html page

You can consider changing the Thank you URL after submission instead. In this way, the URL of the page you want to add in the Thank you Page settings will appear after the form will be submitted.

Here's the guide on Redirecting Users to a Different Page.
