Keep Open in Desktop Layout but toggle in Mobile Layout?

[kevintraver]

Is there a way to keep the menu visible and locked in desktop layout, but then toggle in mobile layout?

You have some control using the isOpen argument which you could combine with some responsive logic in a getter to open it by default on desktop. Locking the menu is currently missing. This would be a nice addition in combination with adding an example to the documentation showcasing how to do this.

Some inspiration can also be taken from empress-blog-hummingbird-template where I customized it to show a different menu on desktop using ember-responsive. See: https://github.com/nickschot/empress-blog-hummingbird-template/blob/master/app/templates/application.hbs
