I don't think a menu toggle can ever work right. The problem is
controlled by two variables, and you would never be able to get back
to the initial state, unless you made it rather complex.

Even if you simplify things by getting rid of
truncate-partial-width-windows, there are still three possible states:
always truncate lines, never truncate lines, truncate only in partial
width windows. You could have a radio button I suppose, but it all
seems a bit much to me.
