form where multiple products and quantities

[Gustavo_Eduardo]

Hi everyone, I'm trying to build an application where I charge sales. Sales carry various products and associated quantities.

Does anyone know a way to make a form where multiple products and quantities can be uploaded?

For example:
Bread x 10U
Cakes x 5U
Donuts x 15U

That is, a drop-down list that is generated after another, with an associated quantity. I appreciate your answers.

Isn't this a typical use case of  "Is APartOf" referential architecture?
