Instantaneous excluding ticks on checkboxes

[LamaKing]

It would be nice to have the exclusive checkboxes, instead of check at the end if there's only one selected.
There should be something made for this propose in NpyScree: SelectOne
I've tried to use something like this in the code:
self.add(nps.TitleSelectOne, name="Choose an option", values=["Redirect", "Forward"] )
But I get an error about on the size of the terminal.
Someone more skilled than me can help? =)
