Deeply nested sidebar

[inormann]

The use case of a website that needs to display a deeply nested table of content (e.g. for an ebook) in a sidebar suggests to allow for the construction of arbitrarily deeply nested submenus. The sidebar component doesn't seem to support this feature: According to the shadn docs for sidebars the component SidebarMenuSub can be used to render a submenu within a sidebar as shown in the example:

<SidebarMenuItem>
  <SidebarMenuButton />
  <SidebarMenuSub>
    <SidebarMenuSubItem>
      <SidebarMenuSubButton />
    </SidebarMenuSubItem>
    <SidebarMenuSubItem>
      <SidebarMenuSubButton />
    </SidebarMenuSubItem>
  </SidebarMenuSub>
</SidebarMenuItem>

This example suggests, however, that only SidebarMenuSubItem can be used as child components and not a regular SidebarMenuItem component. I conclude from this that it is not possible to construct arbitrarily deeply nested submenus? (Correct me if I am wrong)
