Do you need to store the same information in multiple locations or update columns without extra effort? Linking and mirroring boards let you make changes on one board, and updates automatically appear in linked boards.

Increase visibility and centralize all important information with the Mirror Column.

Before starting

To add the Mirror Column, you'll first need a Connect Boards Column. These two columns work hand-in-hand to pull data from various boards and display information from those boards in reflecting columns on your new board.  Connect Boards Column links the items in your boards together, while the Mirror Column reflects information from one (or more) board to another, creating more visibility. 

Adding the Mirror Column

Once you have set up a Connect Boards Column, you can add a Mirror Column. To add the Mirror Column, go to the Columns Center, search for "Mirror" in the search bar, and select "Add to board." 

After adding the Mirror Column, you'll be prompted to link it to a Connect Boards Column on your board. To finish setup, click the blue "Connect" button and choose the Connect Boards Column you want to mirror. 

Choose columns to mirror

The Mirror Column displays data from a selected column on your connected boards. After linking an item with the Connect Boards Column, you can choose which column to mirror.

Click the three dots to the right of the Mirror Column, hover over "Settings", and click on "Customize Mirror Column". You can then select the column you want to display from each connected board.

In this example, our board is divided into three groups, each representing one of the connected boards linked via the Connect Boards Column. We’ve then chosen to mirror their “Status” columns, so the Mirror Column shows each connected item’s status.

Now you can make sure that your connected columns are fully synced at all times! Every time you make a change to one of the cells in the mirror column, it will reflect on the connected board(s) as well, and vice versa. 🙌

Change your Mirror Column

To change the column displayed in a Mirror Column, click the three dots next to the column name, hover over "Settings", and select "Customize Mirror Column". Use the dropdown to select a different column type under each connected board. Changes will apply immediately, and the Mirror Column will update to show the new data from each linked item.

The Updates section cannot be mirrored; however, you can view it by clicking on an item in the Connect Boards Column, then clicking on the three dots in the top right corner of the item card. From here, select the "comment" icon, which will take you to that item's Updates.

Customize your Mirror Column

When mirroring a column, you can customize how it is displayed on the board where it will be mirrored. For example, when selecting the Status Column to mirror, you can customize the column to display either "All labels" or "What's Done." 

Alternatively, if you are mirroring a Numbers column, you can determine exactly how you'd like the reflected numbers to be displayed - as the sum, average, minimum value, etc. 

Each column will have its own set of customization options. Make sure to check them out. 🙌 

Mirror multiple items from the same board

The Connect Boards Column lets you link multiple items from another board to a single item on your current board (e.g., tasks linked to one project). The roll-up feature then neatly aggregates mirrored data from those linked items for a clear, streamlined view.

For example, our item "Venue costs" is linked to several items on the Ceramics Gallery Showcase board. By setting the Mirror Column to show the Status column, we get a combined view of all their statuses.

When multiple statuses are mirrored, the Mirror Column shows only their colors, not labels. Hover to see each status label and the percentage of items with that status. Click on a status color to view the linked items.

Multi-board mirroring

Want to mirror multiple items from different boards into one column cell? With the multi-board mirror feature, you can! First, connect multiple boards and link items using the Connect Boards Column. Then, set up the Mirror Column to view aggregated data from all selected boards in one view.  

In this example, our High-Level board connects to three project boards, organized into groups like "Financial Overview" and "Staff Tasks" to track key areas. Items from each board link to relevant group items; for example, "Venue costs" links to all venue cost items in the three boards. The Mirror Column then shows the status of each linked item. 

Mirroring other Mirror Columns

You can choose to mirror another Mirror Column; however, you can only do this a certain number of times. This prevents potential performance or data issues from excessive mirroring.

Currently, you can mirror Mirror Columns only up to two times. For example, mirroring from "board 1" to "board 2" and then from "board 2" to "board 3" works, but adding a third level from "board 3" to "board 4" does not.
