The classic 777 had folding wingtips as an option but I don't believe it was ever ordered.
The 777 was also offered with optional folding wing tips where the outer 6m/21ft of each would fold upwards for operations at space restricted airports, but this option has never been selected by any customers for the aircraft.

Several military aircraft have inadvertently taken off with folded wingtips with varying outcomes.
