how to make a table filter not appear when it has already been selected.

Hello, good morning, I have a problem, I have a sales table, I already have the reference of my product table, but when I add a product and want to add another product, the product that I already selected continues to appear.
I would like a little help regarding the fact that the product that I already saved continues to appear in the list of products that I am going to sell.
