You can overlay lists with the same content type and lists with matching fields. Every list chosen as a data source for a Kanban board must have at least one choice field and one user field.
Lists can be merged in two cases:
- They have identical content types with the same fields.
- They share the same parent content type. In this case, only the matching fields will be merged—both the field type and field title must be identical in both lists to merge them and make them available to select as Kanban columns, Kanban swimlanes, or required fields in the board settings.
The table below shows the compatibility of list columns. These columns, taken from two or more SharePoint lists, can be merged and used as the following:
- Kanban columns
- Kanban swimlanes
- Required fields for a board (such as the task title field)
For example, if List 1 is a task list with the “Assigned to” field renamed to “Users” and List 2 is a custom list with the “Created by” field also renamed to “Users,” this field (“Users”) will be available on the board as a column or swimlane when both lists are merged.
However, if List 1 has the field named “Assigned to” and its copy, “Copy of list 2,” has renamed the field to “Assigned Users,” these fields will be available to edit and display on a Kanban board, but you won’t be able to use them as columns or swimlanes.
