Header: Option to add mega menus#81

Currently Spark makes use of a secondary menu as part of the drawer menu, in order to allow for a “Featured” list of menu items within the drawer (here’s where to look for an example). But perhaps some folks want a mega menu instead, so here’s where to vote!

definitely agree - mega menus look so good on desktop - it really helps to editorialize the website and really push specific products/categories/themes.
