Menu doppio in js

[muaddib]

Salve a tutti
Inanzitutto mi scuso per la lunghezza del post, ma la mia quasi totale ignoranza di javascript mi ha imposto di inserire tutto il codice. Vorrei gestire un insieme di link divisi per categorie , ma vorrei forzare l' apertura degli stessi in una nuova pagina e non in quella del menu...
Mi potreste dire come e dove modificare il codice per ottenere ciò ??

Put a blank item (like below) for the MAXIMUM
number of items in one of your categories.
i.e. If your "largest" menu contains 5 items,
include 5 blank lines here. For 10, include
10, and so on.
