Args:
option_generator (callable or list): A list of strings indicating the options, or a callable
that is called as option_generator(caller) to produce such a list.
select (callable, option): Will be called as select(caller, menuchoice)
where menuchoice is the chosen option as a string. Should return the target node to
goto after this selection (or None to repeat the list-node). Note that if this is not
given, the decorated node must itself provide a way to continue from the node!
select (callable or str, optional): Node to redirect a selection to. Its `**kwargs` will
contain the `available_choices` list and `selection` will hold one of the elements in
that list. If a callable, it will be called as select(caller, menuchoice) where
menuchoice is the chosen option as a string. Should return the target node to goto after
this selection (or None to repeat the list-node). Note that if this is not given, the
decorated node must itself provide a way to continue from the node!
pagesize (int): How many options to show per page.
