Of one particular Product I have Items with different Expirationdate.

My Idea:

• I can store multiple Expirationdates per Product
• together with the particular Expirationdate I can store the according Number of Items
• the Position in the List reflects the oldest Expirationdate, if the Number of Items of this Expirationdate falls down to 0 then this particular Expirationdate is removed, and the Product's Position in the List changes to the now oldest Expirationdate
• the List should show the Product and the Sum of all Items, and only when clicked on the Product, I can see how many Items for each particular Expirationdate are there

Example:

Chocolate-Cream: 2024-02-17: 2
Olive Oil: 2025-06-28: 2
Kidneybeans: 2026-05-20: 5

When I click on Kidneybeans it shows:

Kidneybeans:
2026-05-20: 2
2027-01-13: 3

Perfect would be Buttons with + and - to in- and decrease the Numbers.
