You can separate menu items with a dash: "-". eg:
Code:
menu status { 
  first
  .something in first : noop
  .something else in first : noop
  second
  -
  third
  .something in third : noop
  .-
  .something else in third : noop
}


You can start with a separator too, e.g. if you want to add a "new" item to an existing menu definition:
Code:
menu status, channel {
  -
  MyScript
  .funktion1 : noop
  .funktion2 : noop
}
