Horizontal to Vertical layout from PureCSS.io site

[cooperdozier]

Years ago, I used the responsive horizontal t vertical menu supplied by the Pure CSS project at https://purecss.io/layouts/tucked-menu-vertical/ . When I needed more menu items than could fit across a wide browser window, I found that I could not adapt the supplied script and eventually wrote my own that supports a submenu and is easy (with instructions) for a person less skilled in JavaScript to adapt to different numbers of menu items. I finally got around to cutting it down from my website's implementation to one with mostly just the essentials (some more decoration could be swept away but having it visible helps debugging). It is now available on GitHub and I'm calling it Easy Em and appears to be compatible with the full Pure 3.0.0 and responsive grids 3.0.0 (i only use a subset). So I thought I would make it known here, and also, if development plans allow for it, propose that this system possibly be included on the Pure website in some capacity.
