I am not getting the proper parent menu item for my navi list.

title one
    subtitle one
    subtitle two
    subtitle three

subtitle one
    subtitle two-one
    subtitle two-two
    subtitle two-three

instead of subtitle two showing up as header for the navi list, subtitle one instead shows up.

Thanks.
