Add ability to toggle sidebar with responsive: true even on screens > 1024px

Hi. Nice performant plugin.

The only thing is missing for me – the ability to toggle visibility in responsive mode on large screens. Would be cool to have behaviour much like Angular Material Sidenav.

It's useful sometimes to expand content to full-screen. Tables with big amount of data, for example.

Currently I've not time to working on, if you want a PR is welcome!
