Sidebar Menu Separator

[justacec]

I have been looking for a way to add sidebar menu separator between some of my sidebar menu items. I would like them all to be top level for visibility, but be gapped just a bit to separate out the logical regions. While a gap would be ok, it would also be great if there could be a rule.

Could be something like:

 bs4SidebarMenu(
  id = "Fun",
  bs4SidebarMenuItem("One", tabName = "one"),
  bs4SidebarMenuItemSeperator(),
  bs4SidebarMenuItem("Two", tabName = "two")
)
