Edit a form without publishing on live instantly

Hi there, I need to make changes to a form without those changes instantly being reflected on the website. How do i do this?

I saw this thread: https://www.jotform.com/answers/127008-Is-there-a-way-to-make-changes-to-a-form-without-it-auto-saving but it isn't very helpful. No screenshots or step by step? Where is the "white part of your form area"?

Thanks, 

Thomas

Please note that the thread you are referring to was very old and the option was available in our earlier version. The current version of JotForm doesn't have such option and features only continuous save option. If you need to revert any change made to the form, you may use Ctrl+Z (undo) while the builder is open or you may use the form revision history.
