WordPress Foundation theme

I have scoured the web for this answer and can’t find it anywhere. Is anyone using the foundation theme, and if so, how do you edit the html in the widgets? It’s using the tinymce editor and I can not for the life of me find out how to edit the html. I have looked at every plugin involved with the site, and clicked on every single link and can not find the option anywhere. Does anyone know how to use this?
