HTML/CSS Horizontal sub-submenu attached to vertical submenu

Question

I am wanting to align a vertical sub-submenu that is horizontal to a submenu, like this:

I am able to achieve this, as the picture shows, but I have to make the position absolute. The problem with that is I would want the top part of each sub-submenu to line up with the top of the submenu it is attached too. For instance, the artist sub-submenu would be exactly the same as the one shown, but would have A to Z lined up with Artist.

In order to do that the way I am doing it now, I would have to create many different css sections, rather than being able to select multiple submenus with one section (for instance #sortsongmenu, #sortartistmenu { styling }. I would like to find a way to have the sub-submenus in the position shown without having to position each sub-submenu separately, but rather have a styling approach that could apply to all sub-submenus that have relative or some other positioning.

HTML code:

<-- CSS code--> 
#topbar {
background-color: #222;
}
#topbar_wrapper {
width: 100%;
margin: 0 auto;
text-align: left;
}

Try:

Change

#sortmenu li {
    display: block;
}

#sortsongmenu, #sortartistmenu {
    display: none;
    position: absolute;
    background-color: #333;
    border: 5px solid #222;
    border-left: 0px;
    text-align: right;
    left: 100%;
    bottom: 65%;
    width: 100px;
}

to

#sortmenu > li {
    display: block;
    position: relative;
}

#sortsongmenu, #sortartistmenu {
    display: none;
    position: absolute;
    background-color: #333;
    border: 5px solid #222;
    border-left: 0px;
    text-align: right;
    left: 100%;
    top: 0;
    width: 100px;
}

EDITED:

Change top to -5px, as your sub submenu have a border top of 5px. It will look better that way.
