Mirror
A read-only view of columns from a connected board or an item's subitems.
3 min readUpdated
A Mirror column does not store its own values. Instead, it reflects values from another source and updates automatically when the source changes. You cannot enter values directly into a mirrored cell.
Choosing What to Mirror#
Open the column's ⋯ menu and select "Settings". After the "Mirror column" introduction, choose a Connect boards column. The list includes Subitems, every Connect boards column already on the board, and "Create a new connection".
Mirroring Subitems#
Select "Subitems". You are then asked to "Select which subitem column to mirror". Choose one of the board's subitem columns, and the parent row reflects the values from that column across its subitems.
Mirroring a Connected Board#
Select a Connect boards column. The settings panel asks you to configure three things:
- The Connect boards column to mirror through.
- Which columns to display from the connected board.
- The display mode: "Show all" or a done count in the format "X / Y done".
