Is it true that after nirvana, no new intentions will be formed by the individual?

I don't know if nirvana is a permanent or impermanent state, but is it true that after nirvana, no new intentions will be formed by the individual? And what is left-over is only a karmic residual of previous living? from the wiki : >> When preliminary nibbana with substrate occurs (that is, nibbana of a living being), constructive consciousness, that is, the house-builder, is completely destroyed and no new formations will be constructed.
