[Typo3] how to create an empty line in a FE menu

[stefano cecere]

it's something i've been trying to do since a lot:

i'd like to insert an "empty" menu voice.. maybe somethin with just a 
  inside, in the FE.., to separate a long menu (see for example 
http://www.ilfannullone.it )

if i create a "divider" in the BE, it is ignored in the FE.
same as for other page types..

did anybody find a simople solution for this thing?

many thanks
stefano
