Door trim (interior door)?

[brevik]

Is it being nailed in the frame?

Screwing works well too.

Is it nailed into the frame?

You nail into the frame and the wall, as well as glue the miter, and if you want, you can also drive a nail from top to bottom into the stand. If the trims are pre-lacquered, 5 nails in the frame and 2-3 in the wall are sufficient. 30 mm nails in the frame and 50 in the wall.
