I have a custom field (dev type). On the Board, I'd like to see all available options in a combobox or some other way. For exanple, there are 20 tickets on the board and all of them have 7 different dev types. So, I'd like to see a list of 7 different dev types. Then I select one of them and I can see only those tickets which have the selected dev type. How can I do that? Thank you in advance.
