Ever try to place a Form in a SharePoint WebPart or Content Editor WebPart. Doesn’t work real hot. In SharePoint 2010 I managed to strip a master page to its bare bones and override some JavaScript Methods and was able to nest a form tag. SharePoint 2013, a different story.
So the basic jest, build the Form virtually on the client in memory using JavaScript and submit it.
There is a sweet piece of JavaScript located here. It will take a DIV tag and convert it to Form and submit it.
