For a recent project I wanted expandable menu functionality similar to how Collapse is used to show and hide menuse with Bootstrap. But I wanted the menu to push out from the side as is done by many mobile apps, rather than the standard collapsible top down menu. What I found was Jasny Bootstrap.

In the end I’m not entirely certain it will do what I want but here’s a quick pen I wrote to play around with its “offscreen” functionality.
