I’m in need of help disciplining my toddler

Zani

Does anyone know anything about disciplinary for a almost 2 year old boy he hits bites scratches he’s really aggressive and I don’t know what else to do I take his toys away tell him no everything from the moon and back he’s mean to other children I can’t take him to any public places without him flipping out in the store because he can’t have candy or toys I just am lost and don’t know what to do me and his dad split up and he doesn’t really come around when I ask him to picture for attention
