Custom field (type related) filters record based on field value

Good morning,

In Products module, I would create a custom field related with Accounts module, but I want that only account with account_type = “myvalue” can be selected.
I don’t want that users when open popup must search accounts using search form, but I would prefer that users have immediately the list with only accounts permitted.

How can I implements it?

Thanks to those who give me suggestions.


Maybe this helps?
