Off-canvas menu in mobile with this kind of design?

[lamagia]

Hi!

I'm looking for a plugin or a widget to replicate this design.

As you can see, there's a main menu (includes Profes, Asignaturas, Más and Blog) and some of these have sub-menus.

These sub-menus, instead of opening under the main element (like if it's an accordion) slide to the right.

There's a "return" button above to get back to the main menu.

Thanks in advance!
