Have you thoroughly read the documentation on fields?(https://nova.laravel.com/docs/4.0/resources/fields.html) This is a multi-step process to set up code & configure how its displayed to achieve something like this using nova admin dashboard, it doable, but I would recommend reading the documentation and then having a go and posting code that you have tried, without this what you are asking is very broad and will be difficult for anyone to help you.
Try setting up a "products" resource & setting the fields in it, referring to the documentation & then ask here if you get stuck along the way.
I'm only learning so I won't be the best to help, but other always do!
