How to add the same item to another board with Mirror Item

Mirror Item Multiple Boards · Updated 20 September 2026

Short answer

Open the item, click the Mirror Item Multiple Boards tab, choose the target board and group, and click Add Item. The same item now lives on both boards, and columns with the same name and type stay in sync both ways.

Before you start

The columns you want shared must exist on both boards with the same name and type. The app does not create columns.
You need edit access on the target board.
If the boards are in different workspaces, the app must be set to All Workspaces. See target board not showing.

Steps

1Open the item you want on more than one board.
2Next to Updates, Files and Activity Log, click the Mirror Item Multiple Boards tab. If you do not see it, click + and add it from your installed apps.
3In Target Board, choose the board where the item should also appear, then choose the Target Group.
4Turn on Add Updates to sync the conversation, and Add Subitems to bring the subitems along.
5Click Add Item.

Mirror to another board panel with Target Board and Target Group dropdowns and Add updates and Add subitems toggles — Pick the target board and group, then choose whether updates and subitems come along.

When it finishes, the Where this item lives table shows every board the item is on and the columns being kept in sync. The first sync on a new board takes a little longer while the app sets up that board.

Where this item lives table showing an item and its subitems linked to three boards with their common columns — The item and its subitems on three boards, with the shared columns in sync.

Tip: Repeat the steps to add the same item to a third or fourth board. It still counts as one item on your plan.
