Answer 2

Add a border-right style to your category, here's the sample working code
#cssmenu > ul > li {
border-right:2px solid #000;
}
#cssmenu > ul > li:last-child {
border-right:0px solid #000;
}

Answer 3

try this in css
.list li{ background:#ccc; position:relative; list-style:none; border-left:#666 solid 1px; padding:10px; }
