how to change single LI 'level2' into 'last level2' for CSS in my accordion menu

Hi,

i have an accordion menu that’s working great its two levels and is completely stylized through CSS,

i have set up the level two so that when it drops down there is a curve at the end of it, this i did through CSS and it works great except on one occasion.
when i have only a single element in my level two it will not be recognized as but rather stays as

i’ve attached two screenshots that will probably explain thins better(with firebug on as well)

image:Problem1: shows my "level2" applying to a single element
image:Problem1: shows the "last level2" working perfectly with 2 elements

so to sum up i want it so that when there is a simgle element appearing in "level2" it is to be treated as a "last level"

does this make a lot of sense to anyone?

thanks very much

Perhaps you could put an image into the <ul> element instead of the <li>.
