How to Bulk Edit Subitems Across Multiple Items in monday.com (2026)

Direct answer: monday.com lets you multi-select subitems inside one item’s subitem list and act on them together, but as of mid-2026 there’s no native way to select and edit subitems across multiple items, so mass updates mean opening each parent in turn. To update columns across every subitem of many items in one pass, use SubItems Pro’s Edit tab: select the parents, pick columns and values, run once.

What can native batch actions do with subitems?

monday.com’s Batch Actions are solid for items: select several (checkboxes, or a whole group at once) and a toolbar appears at the bottom of the screen with duplicate, export, archive, delete, and move. Editing one cell applies the change to every selected item.

Subitems get a slimmer version. Within one parent’s subitem list you can select multiple subitems and act on them from the same bottom menu — monday.com’s own docs show selecting subitems, duplicating them, and moving them to another item. For cleaning up a single parent’s checklist, that’s usually enough.

The wall: as of mid-2026 there is no native way to select subitems across parent items. No “select all subitems on this board,” no board-level subitem table with checkboxes. Requests for exactly this (mass-updating subitems under multiple items at once) have circulated in the monday.com community for years. Native bulk editing of subitems is parent-by-parent work.

Why does this hurt at scale?

Picture a sprint board: 30 items with 5 subtasks each — 150 subitems. Closing the sprint means setting Status on all of them, plus a completion date. The native route is expand item 1, select its subitems, update, collapse, repeat 30 times. Same grind when a teammate leaves and 80 subtasks need a new owner, or when a slipped milestone touches every subtask date in a group. None of it is difficult. It’s 30 repetitions of an easy thing, which is exactly what batch tooling is supposed to eliminate.

How do you bulk edit subitems across items with SubItems Pro?

SubItems Pro’s Edit tab operates at the level native skips: all subitems of every item you select.

1. On the board, select the parent items whose subitems should change — a few, a group, or the whole board.
2. Open the SubItems Pro board view → Edit tab. It loads all subitems of every selected item.
3. Pick a column and its new value, and add more columns to the same run if needed (each column once per run). 17 column types are editable: Status, Person, Date, Timeline, Numbers, Link, Email, Checkbox, Phone, Country, Tags, Rating, World Clock, Week, Text, Long Text, and Hour.
4. Run. Updates are applied in batches across every loaded subitem.

One rule: Edit applies the new value to every subitem of every selected item. You scope the change with your selection, so pick only parents whose entire subitem list should change.

What it costs: one action per subitem edited, so a 150-subitem sprint close is 150 actions. The free plan includes 20 actions per month; paid plans are flat ($8–$118/mo) rather than per-seat. Full mechanics in the user guide.

Example 1: closing out a sprint

Goal: every subtask in the “Sprint 24” group gets Status Done and today’s date in the Date column.

1. Select all items in the Sprint 24 group.
2. Edit tab → Status = Done, and add Date = today in the same run.
3. Run once. Both columns update across all 150 subitems in one pass. That’s the multi-field update doing its job.

Example 2: reassigning a departed teammate’s subtasks

Goal: subtasks owned by someone who left get a new owner.

1. Select the items whose subtasks were theirs — typically their project group or their slice of the board.
2. Edit tab → Person = the new owner.
3. Run.

Careful: Edit sets the value on all subitems of the selected items. It doesn’t filter by current assignee. Where a parent mixes owners, split the selection and handle the mixed parents natively, one subitem list at a time. For most reassignments the clean bulk covers 90% and the native route mops up the rest.

Which tool for which job?

Job	Best route
Update 4 subitems under one item	Native: select within the subitem list
Duplicate a few subitems and move them to another item	Native — see copying subitems
Status → Done on every subtask in a group	SubItems Pro Edit
Reassign an owner across dozens of items	SubItems Pro Edit (watch mixed-owner parents)
Add new subitems in bulk instead of editing existing ones	Bulk-create methods

For a single parent, the built-in multi-select is faster. From the second parent on, the Edit tab is.
