hello, for the app of the studio, I want to add a product from the category of this, but I don't know the way to do this. it comes to put straight the product from your base data, but I want to put it first from a category like a filter and then take the product from this category, after this, I want it to automatic autofill the unit prices and all that stuff, I will attach an example.

In the picture shows the new tab which i add, but it dont work as i want. and i broke the next tab, "Product tab" so it dont put the price of my product automatic anymore.
