Vaadin Framework (Vaadin 8) offers a MenuBar widget, as discussed in the manual, and shown in the Sampler.
When I switch the manual to "Vaadin 10" mode, I cannot find the MenuBar widget. I know Vaadin 10 (Vaadin Flow) is a major re-write of Vaadin, is the widget changed in name or not yet available?
Possibly in Vaadin 14
Update: A MenuBar widget is planned for development by Vaadin Ltd, scheduled for Vaadin 14 release.
- See the manual.
- On GitHub, see Issue # 4694 MenuBar component.
No MenuBar in Vaadin 10 or 11
As discussed in this Forum thread, as of version 11.0.1, Vaadin Flow currently lacks any such menu bar widget.
