MenuBar replacement?

I am very concerned about the statement “it is not on mobile devices”.

we chose vaadin a few years ago because they claimed that it was easy to pass from desktop applications.
It was not that easy but we did it

In fact, our applications today are for desktop. And there are still millions of users who use their PC with preference because they have a monitor “a little bigger” than their cell phone. And they can browse, buy, etc. over the Internet more comfortably.

It seems very good that now support / consider mobile devices. But I worry that vaadin leaves the desktop environment as something strategic.

Thanks!

Best regards
