How to copy, move and convert subitems in monday.com
By Arnav Ghatage, founder of Fortimus · Updated
Short answer
Duplicating an item duplicates its subitems with it. To copy subitems to a different item, duplicate them and move the copies there with Move to. Move to on its own relocates a subitem, and Convert turns a subitem into an item or an item into a subitem. If two teams need to work on the same subitems, copying is the wrong tool altogether and they should be synced instead.
People land here wanting a few different things, and monday.com treats each one differently. Sort out which one you are after and the rest of the page is short.
Which one do you want?
| What you want | Use | What you get |
|---|---|---|
| One more copy of a checklist you reuse | Duplicate | A separate set of subitems. Edits on one side never reach the other. |
| The subitems belong under a different parent | Move to | The subitems leave the first item. Nothing stays behind. |
| A subitem should be a top-level item | Convert | The subitem becomes an item. Column values with no match are lost. |
| An item should sit under another item | Convert | The item becomes a subitem of the parent you pick. Column values with no match are lost. |
| Two teams working on the same subitems | Sync | One set of subitems, visible and editable on every board, always current. |
Duplicate an item with its subitems
This one is built in and it works the way you would hope: duplicate an item, a group or a whole board, and the subitems are duplicated too.
- Click the three-dot menu on the item, or tick the item and use the bar at the bottom of the board.
- Choose Duplicate, and pick whether the updates come along.
- The new item appears below the original with its own copy of every subitem.
Use it for a checklist you run again and again: a launch, an onboarding, a site visit. The two sets are independent from the moment they exist, so ticking off a subitem on one has no effect on the other. That is exactly what you want for a template, and exactly what you do not want for shared work.
Copy subitems to another item
monday.com has no single button for this, so it takes two steps: duplicate the subitems, then move the copies under the other item.
- Select the subitems with the checkbox on their left. You can pick subitems from different parent items at once.
- Click Duplicate in the bar at the bottom of the screen. The copies appear under the same parent.
- Select the copies, click Move to and pick the item they should sit under.
You end up with two independent sets of subitems: edits on one never reach the other, so the two lists drift apart over time. Syncing them is the way around that.
Move a subitem to another item
Moving relocates the subitem instead of copying it: it leaves the first item and nothing stays behind.
- Select the subitem, or several, with the checkbox on the left.
- Click Move to in the bar at the bottom of the screen.
- Pick the item it should sit under.
To get a single subitem onto another board, convert it to an item first (below), then move that item with Move to board.
Put subitems onto another board
Subitems travel with their parent. Move an item to another board and monday.com transfers its subitems automatically.
- Tick the item, or open its three-dot menu, and choose Move to board.
- Pick the destination board and group.
- Map the columns, for the subitems as well as the parent.
Two things to know before you do it on real work. Moving is not copying, so the item leaves the original board. And any subitem value whose column does not exist on the destination board is dropped in the move, so set up the matching columns first.
Convert a subitem to an item
Convert turns a subitem into a top-level item on the same board.
- Select the subitem and click Convert in the bar at the bottom of the screen, or choose Convert from the subitem’s menu.
- Map each subitem column to a column on the board. If the board has two columns of the same type, pick the one each value should go into.
- Confirm. The subitem is now an item on the board.
Check the columns before you convert: a value with no matching column on the board is deleted. To put the new item on another board, move it there afterwards with Move to board.
Convert an item to a subitem
This is how you move an item under another item. It works like the conversion above, in reverse.
- Select the item and click Convert in the bar at the bottom of the screen, or choose Convert from the item’s menu.
- Pick the parent item it should sit under.
- Map each column to a subitem column. Values with no matching subitem column are deleted.
Worth knowing: copying a column value between a parent and its subitem is a one-time copy. Change the parent afterwards and the subitem does not follow, and the other way round too.
If the task should stay an item on one board and also show up as a subitem on another, converting is the wrong tool. Mirror Item can put an item on another board as a subitem under a parent there and keep the two in sync. See how to mirror subitems in monday.com.
Add subitems to subitems
You can, on a multi-level board. monday.com supports up to four levels of subitems, so a subitem can have subitems of its own, and so on down to the fourth level. Multi-level subitems only work on newly created multi-level boards, so an existing board can’t be switched over. The steps are in monday.com’s guide to multiple levels of subitems.
When a copy is the wrong tool
Every native option above produces a snapshot. That is fine for templates and reorganising. It falls apart when two teams need the same subitems: delivery ticks off a task, the client board still shows it open, and within a week nobody trusts either board. The give-away is that you find yourself updating the same subitem twice.
What you want then is one set of subitems that appears on both boards. That is what Mirror Item Multiple Boards does: the subitem is not copied to the second board, it lives there, and an edit in either place is the same edit.
Step 1: Install the app and match your columns
Install Mirror Item Multiple Boards from the monday.com marketplace. There is a free plan. Subitem columns sync by matching name and type, so there is no field mapping: give both boards subitem columns with the same names and types, and anything named differently stays private to its board.
Step 2: Open the item and turn on Add Subitems
Open the parent item, click the Mirror Item Multiple Boards tab, choose the target board and group, and switch on Add Subitems before you add it.

Step 3: Click Add Item
The item and its subitems appear on the second board with their structure intact. Edit a subitem on either board and both show the change. New subitems added later sync too.

Subitems do not count towards your item limit: a parent item and all its subitems count as one.
Put a single subitem on another board as a full item
A subitem does not have to stay a subitem. Open the subitem itself, click the Mirror Item Multiple Boards tab and add it to another board, where it appears as a top-level item. Managers get each task as its own row on a leadership board instead of buried under a parent, and it stays in sync with the original subitem both ways. The same subitem can also sit under two different parent items at once.

Do it automatically
To stop doing this by hand, open the Automation Center on the board, search for "mirror item" and pick a subitem recipe, such as mirroring every new subitem to another board as an item. New subitems then land on the other board on their own.

Frequently asked questions
How do I copy subitems in monday.com?
Select the subitems and click Duplicate in the bar at the bottom of the screen. To put the copies under another item, select them and use Move to. Duplicating a parent item also duplicates its subitems. The copies are independent: edits on one set never reach the other.
Does duplicating an item in monday.com duplicate its subitems?
Yes. When you duplicate an item, a group or a whole board, the subitems are duplicated as well.
Can I copy subitems to another item?
Yes, in two steps: duplicate the subitems, then select the copies, click Move to and pick the other item. The copies are independent of the originals. If you want the same subitems under two parents and kept in sync, that is what Mirror Item Multiple Boards does.
Can I copy subitems to another board?
Duplicate the parent item, which duplicates its subitems too, then move the copy with Move to board. You map the columns as you move, and subitem values with no matching column on the destination board are dropped unless you add them as new columns.
How do I move a subitem to another item in monday.com?
Select the subitem, click Move to in the bar at the bottom of the screen and pick the new parent item. It leaves the first item. To keep it in both places, duplicate it first and move the copy.
How do I turn an item into a subitem in monday.com?
Select the item, click Convert, pick the parent item it should sit under and map its columns to the subitem columns. Values with no matching subitem column are deleted.
Can I convert a subitem to an item on another board?
Not in one step. Convert puts the new item on the same board, so convert it first and then use Move to board. If the subitem should stay where it is and also show up as an item on another board, Mirror Item Multiple Boards does that and keeps the two in sync.
Can subitems have their own subitems in monday.com?
Yes, on a multi-level board. monday.com supports up to four levels of subitems on boards created as multi-level boards. An existing board cannot be switched over, so create a new multi-level board for this.
What is the difference between copying and syncing subitems?
A copy is a snapshot: two sets of subitems that start identical and drift apart as people edit them. Synced subitems are one set shown on several boards, so a change made anywhere is the change everyone sees.
Do synced subitems count towards my item limit?
No. Subitems do not count towards the item limit on Mirror Item plans. A parent item and all its subitems count as one.
Can the same subitem sit under two different parent items?
Yes, with Mirror Item Multiple Boards. The subitem stays one subitem under both parents and stays in sync in both places.
Why can a mirror column not show my subitems?
A mirror column carries values from a connected item, not a structure of subitems, and subitems live on their own hidden board. That is why mirror columns can show a rolled-up subitem value but cannot put the subitems themselves on another board.
