I could not find a good replacement for my companies drop down menu that was created in Dreamweaver ages ago.
The menu had to mimic the original and work decently in IE9.
A lot of the CSS classes and id’s can probably be removed.
It uses the CSS pre-possessor LESS because it needs to run on a SharePoint custom site and SharePoint defaults to using LESS.
To see it work, go to CodePen.io
