Kanban board - Hiding subtasks in just Done column

[Steven Yong]

I am using Kanban board and my filter is now:

project in (SA, SL) AND type != Epic AND (resolution is EMPTY OR resolutiondate >= -15d) ORDER BY Rank ASC

I do not want to see subtasks in the Done column but other column is OK, is this possible?

[Nic Brough -Adaptavist-]

Add the clause

AND NOT (issuetype in subtasktypes() and status in (x, y, z))

where x, y, z is the list of all the status in your "done" column.

Thanks @Nic Brough -Adaptavist-, it works but I need to use

issuetype in (Sub-task)

or 

issuetype in subTaskIssueTypes()
