|Name||D8||Personally Tested||Last Updated|
|Responsive and off-canvas menu (responsive_menu)||✔||✔||2020-11-18|
This uses a JS library and works without a second copy of the menu in the HTML, and you don't need to make any changes to your existing navigation menu.
Look at the README file for instructions.
Note you're forced with the mobile version of the menu to have it expand to full depth (although the hack/workaround, if you want a top-level menu only, is to hide the lower elements in CSS)
