Fecth records in a subform depending on a field in the form

Fecth records in a subform depending on a field in the form

Hi, I am developing an order management application.  We want to have all the product pre-loaded so the user doesn´t forget any item. 

For user experience reason, we want to show him the products of a specific category. 

I am pre-creating all the products in the subform, but I want to fetch the records to show just the information of a specific category choosen by the user. 

It is possible to do it. How could I do that?

Thanks,

Mari
