In order to not render the extra div that is created by Html.PropertyFor, I have implemented the custom content area renderer as per the articel from jon d jones.

However, even though I can see that it goes to the correct part of the renderer, where it should not add extra div, in the end there is an extra div.

else
                        {
                            htmlHelper.RenderContentData(content, true, templateModel, contentRenderer);
                        }

Does anyone have a clue how to not get the extra surrounding div?
