I am looking at this api page for MenuBar:
However, it seems its available on version 1.4, while at Github, there is only 1.3 of FeathersUI
Any advice is highly appreciated, we need a drop list or a menu bar.
I suspect this feature will be included in FeathersUI 1.4.0, but that has yet to be released.
You could try installing the git version for now, which should give you access to that feature, at least until 1.4.0 is released.
