I am thinking that this plugin should work. I was able get checkboxes to come up in posts.
But, what I really want to do is integrate mc4wp checkboxes into my already existing CF7 form. Which I think is the point, but I think I am missing the point somewhere.
http://pastebin.com/ZtY6Kn8X%20 is the entire code, and this form is actually send me my wordpress admin email a note.
Just comes to me in text....Is there a way to integrate the MC4WP checkboxes somehow so that if they check those boxes that they will get added to the list?
