If you've ever tried to build an automation based on a Mirror Column in monday.com, you've hit this wall:
You set up the trigger. You test it. Nothing fires.
That's not a bug — it's a fundamental limitation of how Mirror Columns work in monday.com, and it trips up a lot of teams.
Here's what's happening, why it matters, and the actual fix.
What Mirror Columns actually are
A Mirror Column doesn't contain data. It's a window into a column on another board, via a Connect Boards relationship.
When a value changes on the source board, the Mirror Column reflects that change — but the change event belongs to the source board, not yours. So monday.com's automation engine on your board never sees a change happen. There's nothing to trigger from.
This means:
❌ "When Mirror Column changes → do something" doesn't work
❌ You can't use a mirrored Status to trigger a notification or move an item
❌ Formulas that reference Mirror Columns can produce unexpected results
❌ Forms can't write to Mirror Columns
❌ Mirror Columns don't show up on mobile
These aren't edge cases. They're everyday workflow blockers.
The workarounds people try (and why they fall short)
Workaround 1: Copy mirror value to a regular column via automation
You add a regular Status column alongside the Mirror Column, then try to automate: "When Mirror Column changes → copy value to Status column." But this fails for the same reason — the mirror change doesn't trigger the automation.
Some teams use Make or Zapier to watch the source board and write back to a regular column. That works, but it's complex, costs money, breaks when field names change, and introduces sync delay.
Workaround 2: Restructure your boards so the data lives natively
This is the "right" answer in theory. If you need to trigger automations from a value, that value should live natively on your board, not be mirrored in. But in practice, teams have established boards, existing data, and workflows they can't just tear down. You'd essentially be rebuilding your workspace to work around a column limitation.
Workaround 3: Just duplicate the item across both boards
Now you have two separate items that drift out of sync the moment anyone updates one of them. Updates threads are separate. Subitems are separate. Automations on one don't know the other exists.
The actual fix: make the item live on both boards natively
The reason Mirror Columns exist in the first place is that monday.com items belong to exactly one board. Mirror Columns are a workaround for that constraint — but they come with all the limitations above because they're not actually on your board.
The real solution to needing the same item on two boards is to have the item genuinely exist on both boards, with its own native columns on each one.
This is what Mirror Item Multiple Boards does.
Instead of reflecting data through a read-only column, the item itself lives on both boards. The columns on each board are real columns — not mirrors. So:
✅ Automations trigger normally from any column on either board
✅ You can edit the item from either board
✅ Updates and comments sync across boards automatically
✅ Subitems sync across boards
✅ Formulas, forms, and integrations all work as normal
How it works
Setup takes about 30 seconds:
Open any item → click the Mirror Item Multiple Boards tab in the item view
Choose a Target Board and Target Group
Toggle on Add Updates (syncs comments) and/or Add Subitems if needed
Click Add Item
That's it. The item now lives on both boards. Any column with the same name and type on both boards will sync automatically — no manual column mapping. The app auto-detects common columns and keeps them in sync, two-way, in real time.
For bulk mirroring: select multiple items on a board → click the Apps bar that appears at the bottom → choose Mirror Item Multiple Boards. You can push an entire group to another board in one click.
For automation-driven workflows: there are 25+ pre-built automation recipes. For example:
When status changes to "Ready" → mirror item to Operations Board, Ready Group
When item is created in Sales Board → mirror item to Master Board
When person is assigned → mirror item to their team board
Since the item lives natively on the target board, any further automations on that board trigger normally from that point.
