Thanks Ciaran.
I got your advise, I tried the code. Unfortunatly even if the single menu size is smaller, the submenu moves away from the other menu on its left.
See image "170px.png" attached. Is it possibile to reach the same risult of the 170px case, but with a slight overlapping of the menus?
For best understanding please refer to cutted.png image.
Alternately, the best thing would be to bring near the items of the top menu. See image top-menu.png.
For your help, this is the URL:
