How to Create & Connect Boards in Monday.com: The Connect Board Column and Mirror Column Explained

Board and mirror columns are two of the most useful features in monday.com once a single board stops being enough. This guide walks through creating a board, connecting boards with a connect board column, and using mirror columns in monday.com to pull data across without leaving the board you're working on. By the end, you'll know how to build a fully connected board structure instead of a pile of disconnected boards.

What Is the Connect Boards Column in monday.com?

A connect board column is a feature built for one job: linking items on a board to items elsewhere. Once added, it behaves just like any status or date column, except each cell holds a reference to items linked in from elsewhere instead of typed data. monday.com's own documentation on the feature covers the mechanics in more depth than we will here.

This removes a dependency that used to require a spreadsheet or a manual list: two teams working on separate boards can still see how their work relates without merging everything into one place. A connect board column allows you to connect two systems that would otherwise never talk to each other. If Board A wants to connect items to Board B, a connect board column is what makes that possible, and a mirror then allows you to link a piece of that connected data directly into view.

Every mirror depends on a connect board column already existing on the board; you can't set one up without the other, which is why the two are almost always discussed together. Anyone who wants to connect their first pair of boards should start there before touching anything else, and if boards and columns themselves are still new, our step-by-step guide for beginners covers the groundwork first.

How Do You Add the Connect Boards Column to a Board?

Open the board where you want the new column, click the “+” icon at the end of your columns, and open the Column Center. Search for “Connect Boards” and select it; adding a connect boards column this way takes under a minute once you know where to look.

A panel appears asking you to choose which boards you want to link to. Select boards from the list, then click “Connect boards” to confirm — this is the step people mean when they say click connect boards to finish setup. If you're still deciding boards you want to connect to later, that's fine too; the number of connect boards columns a board can hold isn't limited to one.

Create a connect board column once per relationship you actually need, rather than one for every possible pairing. Each connect boards column links to a specific target, and connect information flows through it the moment items get linked, so there's no separate step to sync anything manually afterward. If you don't see the option to select “Connect boards” in the corner of the setup panel, try zooming your browser out a notch; a single connect boards column isn't locked to whatever board you want today, so mistakes here are easy to fix later.

How Do You Create a Two-Way Connection Between Boards?

When you first connect boards, a checkbox appears for enabling updates in both directions: leave it checked, and changes flow automatically from then on. Skipping it creates a one-directional link instead, which is fine for some setups but usually not what most teams actually want once they think it through.

Say you have two boards: a Sales board and a Projects board. Once connected your boards this way, closing a deal on Sales can immediately show up as a linked item on Projects, and the reverse holds too if the connection runs both ways. That's the whole appeal of board connections done properly.

If you skipped that option initially, you're not stuck. Click the three dots at the top of the column, open column settings, and the same panel that set things up the first time is right there waiting.

How Do You Add a Mirror to Show Connected Data?

A mirror column pulls a specific field from a connected item and displays it directly on your current board, without duplicating the data itself. Change the value on the source board, and the display updates automatically; it's read-only wherever it appears, by design.

To create a mirror column, search for it from that same menu. If your board has more than one connect boards column, you'll be asked which one to use before picking which column to display from the connected board. Most column types can be used this way: status, people, numbers, dates, and more. The item name column is the main exception.

Adding a mirror column makes the most sense once you already know exactly what you want to mirror. Guessing and adjusting later works fine too; changing the source takes the same few clicks as the original setup. Use mirror columns sparingly at first, since a board with too many of them gets just as cluttered as one with too many typed columns.

How Do You Link Items Between Connected Boards?

Once boards are connected, click any cell in the column to reveal items from the linked board and link items from there. The connect boards column on the target board is what actually opens that search panel showing items on another board, and you can link a column's cell to one or more items at once if a single row relates to more than one thing elsewhere.

Items across boards stay tied together as living references, not static copies once linked this way. If someone renames an item on the source board, that update carries through everywhere it's referenced. The single-source-of-truth idea that sales teams talk about constantly applies just as much to boards as it does to contact records: keeping data between boards accurate only works when there's one real copy of it, not several scattered around.

For teams tracking items in board after board, this single mechanic is usually the difference between a genuinely connected system and boards that just happen to sit in the same account. Items from one board show up automatically, and items from the connected side stay just as current, so the whole setup reflects reality instead of whatever was true the last time someone remembered to update it.

Why Connect Multiple Boards Instead of Using One Big Board?

Cramming everything onto a single board eventually breaks down: too many columns, too many groups, a board that takes forever to load. Splitting work across multiple boards keeps each one focused, and connections to other boards handle the relationships between connected pieces of work without losing visibility.

A common pattern is a board per client or department, with a shared view rolling activity up from each one into somewhere central. Linked boards this way behave like filing cabinets that still know about each other rather than one drawer stuffed with everything at once. Individual project boards stay lightweight for the people doing the work, while a summary elsewhere shows the picture across connected boards. How other platforms handle project dependencies runs into this exact same problem, just with different terminology.

This scales further than it looks at first, since you're not limited to referencing just a single board; different boards across the account can all feed a single hub, effectively pulling boards into one coherent view without physically merging any of them, or handling multiple boards simultaneously from a single connected column.

How Do You Use This for CRM and Project Management?

For sales work, a connect board column turns a plain contacts board into something closer to a real system: link a deal on a sales board to the account it belongs to, and deal stage can show up right next to contact details without opening a second tab.

Project management setups lean on the same mechanic differently. Teams managing several client engagements at once often keep a board per client and a master board that reflects status across all of them, since managing complex, interrelated work by hand gets error-prone fast. Any setup that involves interrelated boards benefits from this same pattern, whether the work is sales, delivery, or something else entirely, and column choices along the way are usually boards based on what leadership actually needs to see.

The two use cases share a common thread: both need one place that reflects reality across separate systems without forcing anyone to maintain the same information twice.

How Do You Automate Updates Between Boards?

Automation and connected boards pair naturally: a rule can watch a status change on a board and update the connected item elsewhere, so a manual step disappears. Search “connect” in the recipe library and several ready-made options show up for cross-board updates.

Depending on your workflow, you might set something up as simple as a board automatically notifying a linked item's owner when a status changes, or something layered like keeping a due date in sync across several connected boards at once. Either way, the rule sits on top of the structure you already built; it reacts to the connection rather than replacing it. The same logic extends outside monday.com entirely once you bring connectors into it, which our guide to the best monday.com integrations covers in detail.

Getting this right usually takes a little trial and error the first time, mostly around making sure a trigger maps cleanly to the right field on the other board rather than firing against the wrong column. Our wider look at business process automation covers this same trigger-and-action logic outside of monday.com specifically, and our workflow management guide covers the planning side of getting a multi-board setup right in the first place.

What Limits and Permissions Should You Know About?

Every connect board column has options worth understanding beyond initial setup: how many boards feed it, whether the connection runs one way or both, and how it behaves once a source item gets deleted. Column options like these live in the same menu you used to build the column in the first place.

Limits exist too, and they vary depending on your plan: how many items one connect boards column can reference, and how many separate connect columns a board can hold, both scale with your monday.com subscription tier. Our breakdown of monday.com pricing covers where each tier's ceilings sit. monday.com supports fairly high limits on most paid plans, but it's worth checking before building a structure that assumes unlimited scale. Our data analytics work often starts by mapping exactly this kind of board structure before anything gets built.

Workspace-level access matters as well. A board connection can only reach boards the connecting user actually has access to, so a column that looks broken for one teammate but fine for another is usually a permission gap, not a bug.

Set Up the Right Way the First Time? Here's Where a Partner Helps

As an official monday.com partner, VisioneerIT builds exactly this kind of board structure for clients who'd rather not spend a week figuring this out through trial and error. Our monday.com support hub handles setup questions with three free queries before anything costs a thing.

For situations more involved than a couple of connections, our project management support helps design a structure that scales past five or ten boards without turning into a maintenance headache, and a workflow and process improvement review often finds a few extra rules worth building once the connections themselves are solid. Our broader guide to getting more out of workflow automation covers related ground beyond monday.com specifically. Want a second set of eyes on your setup? Get in touch and we'll take a look.

Frequently Asked Questions

Do I need a connect board column before I can add a mirror? Yes. A mirror always needs an existing connection to pull data from, so set that up first if you haven't already.

Can one board connect to more than one other board? Yes. Nothing limits a connect board column to a single relationship; you can build a hub-and-spoke structure from one central board out to several others.

What happens if I delete a connect boards column by accident? Anything depending on it stops working immediately, since there's no longer a source. Re-adding the connection and reselecting those fields usually fixes it within a couple of minutes.

Does this work the same way on every monday.com plan? The core mechanic is identical everywhere; only the number of items and connections available changes with your subscription tier.

Key Things to Remember

• A connect board column links items between boards; a mirror then displays a chosen field from that connection, and the second always needs the first in place already.
• Set up updates in both directions unless you specifically want a one-directional link, since most real setups need visibility from both sides.
• Item names can't themselves be mirrored; almost anything else can.
• Splitting work across several connected boards usually beats one enormous board once a team or project grows past a certain size.
• Automation recipes built around “connect” handle a lot of the manual updating that would otherwise fall on someone by hand.
• Options, limits, and access levels all live in the same three-dot menu on every column you build this way, so it's worth learning that menu well.
