Milonic JavaScript Menu

It doesn't work or i don't know where i need to put it in the script.
This is my longest submenu:

addmenu(menu=["form-uitvoering",
,,260,1,"",plain_style,,,effect,,,,,,,,,,,,
,"Acquisitieformulier",rootdir + "ISO-9001/9001.html",,,1
,"Inzamelen-oud-papier-verenigingen",rootdir + "ISO-9001/9001.html ...

Last day i have downloaded the frames based menu. Only there is a problem when a menu item exists from a sub-menu with32 items. It is possible add scrollbar to this.

greetings
