title: How do I fetch specific data when I select an option? MERN Stack
body: <p>I want to make a MERN application for car sales. Every car has its own brand and model. I want that when I select a brand, for example BMW, to get BMW models such as X3, X6, Serie 3 ... When I select Audi, the model should be A6, A5, Audi 80 ... How to do it? How do you make a mongoose model for something like that? Can anyone give me an idea how to do something like that. Nothing comes to mind at the moment.</p>
