Nikon d7000 has no small green rectangular frame after focusing successfully.

In files P, A, S and M, regardless of whether the camera AF area mode adopts single-point AF or 3D tracking, the focusing system only displays one focus point. Even if dynamic area AF(9-point dynamic area AF, 2 1 point dynamic area AF, 39-point dynamic area AF) is adopted, only one focus point is displayed, and other auxiliary focus points are working, but will not be displayed. When the camera selects the automatic area AF, the camera will automatically detect the focus according to the contrast of the background, and at the same time, the camera will automatically detect people from the background (instruction P95 page) and display them at the same time, so as long as there are more points in Gao Fancha within the framing range, the camera will automatically detect more focuses. When shooting in automatic mode, the focus mode adopted by the preset program inside the camera is automatic area AF, so multiple focus points will be displayed.

Select the autofocus area mode as shown below until Auto is displayed on the shoulder screen:
