Share an Item Manually
Choose a destination from the item view:1
Open the item and click the Same Item Multiple Boards tab
Click the item you want to share to open its detail view, then click the Same Item Multiple Boards tab at the top. If you don’t see the tab, click the + at the end of the tab row and add it from the Item Views Center (search “Same Item Multiple Boards”), or ask your board admin to add it.

2
Click "Share to another board"
If the item isn’t shared anywhere yet, you’ll see “This item doesn’t live on other boards yet!” — click the blue Share to another board button.

3
Pick the workspace
A picker opens listing your workspaces. Click the workspace that contains the board you want to share to.

4
Pick the destination board
Click the board where the item should also live. The board you’re on now is grayed out — an item can’t be shared to its own board.

5
Pick the group
Choose which group on the destination board the item should be added to.

6
Complete sharing
Complete any sharing prompts and wait for the item to appear on the destination board. Supported columns with matching names and types sync automatically; there is no manual column-mapping step.
7
Done — the item now lives on both boards
A progress bar runs for a few seconds, then the SIMB view lists the item’s Current Board and every board it’s Also on, plus the columns being synced.

What Happens After Sharing
Once sharing finishes, the item appears in the group you selected on the destination board. Any columns that share the same name and the same column type between the two boards will start syncing automatically — change a Status on one board and it updates everywhere the item lives. Columns that don’t match won’t sync, but they won’t block the share either. You can also add Shared Boards 🔒 from the Column Center to share from the item row and see board-name chips.Visual Indicator

Merge an item with an existing item
If the same piece of work already exists as a separate item on another board, you can link the two instead of creating a new copy. No new item is created. From then on, the two stay in sync.1
Open Item Settings
Open the item, go to the Same Item Multiple Boards tab, click the Settings (gear) icon, and open Item Settings.
2
Start the merge
Under Merge with an existing item, click Merge this item with another item.
3
Pick the other item
In step 1 of 2, pick the board, group, and item that is the same piece of work, then click Next. Some items can’t be picked: subitems, items on the same board, items on a board this item is already synced to, and items that are already synced elsewhere (unlink them first).
4
Choose the values to keep
In step 2 of 2, for the name and for each shared column that differs, choose which item’s value both items will have. Use all picks one side for every row. Columns SIMB can’t copy keep their own value on each item. Subitems and updates are not merged; each item keeps its own.
5
Click Merge items
Read the warning, then click Merge items. If a column can’t be copied, the result lists it and you can fix it on the board.
Remove an Item From a Specific Board
You can remove a shared item from a single board right from the Same Item Multiple Boards item view. SIMB gives you two choices — Unlink (stop syncing but keep the item intact everywhere else) or Delete (permanently remove that board’s copy).1
Open the item
Click the item you want to remove from a board.
2
Open the SIMB item view
Go to the Same Item Multiple Boards tab inside the item — it lists every board the item currently lives on.
3
Click the trash-bin icon
Find the board you want to remove the item from and click the trash-bin icon next to it.

4
Choose Unlink or Delete
Pick the action you want:
- Unlink — removes the item from that board and stops syncing it there, but keeps it fully intact and synced on every other board. Nothing is lost.
- Delete — permanently removes the item from that one board.

Unlink only affects the board you chose — the item stays live and synced on every other board it was shared to. Use Delete only when you want that board’s copy gone for good.
Column Requirements for Syncing
SIMB syncs column values between boards when both of the following are true:- The columns have the exact same name (case-sensitive)
- The columns are the same type (for example, both are Status columns, both are Date columns, and so on)
Formula and Mirror columns are not supported for syncing, and neither are certain other special column types. Values in these columns won’t carry over even if the names match. Connected Boards syncs unless the two columns connect to completely different boards (no board in common); in that case that column is skipped.
