my macbook pro is early 2017(A1707) I lost something on my macbook,and my screen broken when I closed macmacbook !how can i fix it? buy which part can fix this…….

The display on the Retina is not repairable, it has to be replaced. Parts for this machine are just not available yet. To prevent the cracks from spreading I would paint it with clear nail polish or better take it to a auto glass repair shop and get them to help repair it. This display, when you can get it will probably cost at least 1/3 what the machine cost.
