Nested menubar menu

[Computermatronic]

Is it possible to have nested menubar menus like the below?

Yes — this shipped in 4.0.0, and sorry it took a while to get back to you.

Menubar gained the same submenu family the other menus have:

<BbMenubar>
    <BbMenubarMenu>
        <BbMenubarTrigger>File</BbMenubarTrigger>
        <BbMenubarContent>
            <BbMenubarItem>New</BbMenubarItem>
            <BbMenubarSub>
                <BbMenubarSubTrigger>Open Recent</BbMenubarSubTrigger>
                <BbMenubarSubContent>
                    <BbMenubarItem>Project A</BbMenubarItem>
                    <BbMenubarItem>Project B</BbMenubarItem>
                </BbMenubarSubContent>
            </BbMenubarSub>
            <BbMenubarSeparator />
            <BbMenubarItem>Exit</BbMenubarItem>
        </BbMenubarContent>
    </BbMenubarMenu>
</BbMenubar>

They nest as deep as you need, with roving focus and typeahead, and the submenu flips side when it would run off the viewport edge.

BbDropdownMenu and BbContextMenu got the matching Sub/SubTrigger/SubContent trio in the same release, plus radio items across all three and checkbox items on the context menu, so the three families behave the same way.
