– This is not a builtin functionality of ACF so the simple answer is no. That said, it is always possible to create custom functionality. So you could create a submit button which uses a custom submit function. This function could create a new autosave and then redirect to a url with the preview ID. This would require a lot of logic and will not be easy.
– Yes, please look over the docs for the acf_form function, you will see a before and after argument where you can add to the HTML
Thanks for your answer. I realize that I did not put one part of my questions correctly…
Can I wrap just some of the html elements in a div so that I would have a div as a container for some of the fields. Hope this makes sense
