Those specs are for a separate pop-up window, nothing to do with the menu. That is controlled, in part, by things like:
.sub
{
list-style-position: inside;
list-style-type: none;
margin: 0px 0px 0px 40px;
padding: 0px 10px 0px 10px;
border: 1px outset #000000;
position: absolute;
background-color: #ffffee;
display: none;
visibility: hidden;
width: 10em;
} I suggest you do some research on CSS as well as on Javascript.
