Hey jeezyo thank a lot!
it seems that the width of each menu item is hardcoded. I thought it may be calculated on the fly based on the text caption.
If anyone has the same problem, I found at
#nav ul ul a {
background: #222;
color: #fff;
width: 180px;
height: auto;
}
that playing with the width attribute and adding “font-size: 0.80em;” the thing looked decent.
Thanks for your advice!
