Hello, I am studio Module, so i want to add and field which I want to put the category of a product to then choose one of the product in this category.

the problem is I tried to make it but I just broke the thing, because before I could put the product and automatic the program put the price which I captured before in this product.

I want to put the category first, then the product inside this category and the need the program to capture automatic the price which I have.

I will attach a picture.

In the picture you can see the new field which I add so I need it to use it to put a category then in the product list I just need the product which are in the category which i put before.

thank you
