I think I wasn't clear enough about the question. I know there are lots o javascript tools to do drag and drop. What I want is a drag and drop tool that generates HTML5. So, for instance, I can drag an image, configure its position etc and, the same I could do for a text and at the end I'll have an HTML as output. So, basically, it's a drag and drop editor for HTML5. Just like wix do, canva.com etc. Do you know any open source project like that? So that I could take it as a start point?
