Once I publish will I be able to edit the already published form

I am thinking that once I get the form to where I like it I will publish it on my website. Is that the next step? Once I publish will I be able to edit the form on your site (while version 1 is working on my site) and then publish a new version seamlessly?

Yes.

You can just edit your form in your Form Builder anytime. The changes will automatically update your website published form.

@jonathan I want to say thanks to you, I have the same question but I got this answer :)
