I have two tables, - table 1: list of course editions and other course edition information - table 2: list of states in which the course can be found, linked to table 1.
I have set up the kanban display in table 1 based on the linked field in table 2, it only shows me the columns of the states for which there are courses that I display and not the states that are not currently assigned to any course.
With the kanban based on a single select field type, I can also see columns that do not contain courses.
Am I doing something wrong? Is there any way I can also see 'empty' columns based on a linked field?
