: There is a reasonably common phrase, "[something] has legs." I'm wondering if it means, figuratively, that something is strong, agile, or has endurance.

: Does anyone know for sure which is meant? And, out of curiosity, what's the derivation.

Yes, you got it--strong or has endurance.
It is usually said about a film or play. Many times a film will open with strong ticket sales and if the ticket sales stay strong then the film is said to "have legs"-meaning the inherent goodness of the film can carry it instead of just a flash of curiosity.
