Drop Down Custom Fields

[curdiales]

I need a custom field of drop-down list type used for my Trello cards.

I want the drop-down content to be different depending on the card.

For example Card A. Custom field (Serial Number): Drop-down list with the following elements: 12345566 89997777 Card B.

Custom field (Serial Number): Drop-down list with the following elements 56778889 00000000

Unfortunately, I can't do this now, because I get the same elements on all cards Translated with DeepL.com (free version)

Since custom field definitions is held at the board levels, the changed will be applicable to all cards.
