Checking if a specific column contains the selected list of values

[BachDinh]

Hi, 

As a part of larger measure, I want to be able to tell the number of days in which a store has sold at least 1 of each from the user-selected products. 

The default PowerBI interaction is that selecting multiple products will return the sales of any of those combined, so if an user selectes 3 products, it will display sales even if there's a day where only 1 or 2 of those were sold. 

I am looking to only include dates and sales where all 3 were sold, could someone help me find a solution to this? 

Was looking at the CONTAINS function, but the value parameter only accepts a singular scalar value and not a set.
