Create subitems automatically

Create subitems automatically

TL;DR: Generate subitems on demand — when an item's status changes, when a parent column gets values, or when a subitem is created with defaults already applied. Pick the recipe that matches your trigger and what should be created.

When to use these automations

  • Standardised checklists — every new project should auto-generate a fixed list of subitems
  • Templated workflows — status flips spawn the next batch of work
  • Defaults on creation — every new subitem gets an owner, a date, or a name pattern automatically
  • Cross-board generation — creating a subitem here triggers an item or subitem somewhere else

Recipes for creating subitems on a trigger

Recipe (exact text from automation center)
Use when
Deep-dive
"When item's status changes to something, create a subitem on this item in this board."
The simplest case — one fixed subitem per status change.
—
"When status changes to something, create a subitem on this item in this board and map values where both column name and type match."
Same as above but the new subitem inherits matching parent column values.
—
"When item's status changes to something, create subitems based on the labels in this dropdown column (the labels will be the name of subitem)."
One subitem per dropdown label — labels become subitem names.
 Auto-create subitems from dropdown labels⁠ 
"When item's status changes to something, create subitems based on the text in this text column (the text will be the name of the subitem)."
Same idea but reads names from a Text column instead of a Dropdown.
—
"When status changes to something, create X subitems on that item with the name of the label."
Spawn N subitems at once, all named after the triggering label.
—
"When item's status changes to something, create a subitem on the item with the same name in this board and map values where column and name match."
Cross-board create — subitem appears on the matching item in another board.
—
"When subitem is created, create a subitem on this item in another board with the same name."
Mirror new subitems into a parallel board.

Recipes for setting defaults on creation

Recipe (exact text from automation center)
Use when
Deep-dive
"When subitem is created, assign creator as owner."
Auto-ownership — whoever made it owns it.
 Auto-assign the creator as the subitem's owner⁠ 
"When subitem is created, set owner to value."
Hard-assign every new subitem to a fixed person.
—
"When subitem is created, add name of its parent item as a prefix to its name with this connector."
Subitems read clearly outside their parent context (cross-board reports).
 Add parent name as a prefix to subitem names⁠ 
"When subitem is created, link it to its parent item using this logic."
Auto-populate a Connect-Board column on the new subitem.
 Link subitem to its parent on creation⁠ 
"When subitem is created, create an item in another board and connect using connect column."
Cross-board ripple — a new subitem here creates a new item there.
—
"When subitem is created, remove (copy) from its name."
Cleanup — strips the "(copy)" suffix  monday.com  adds to duplicated subitems.
 Auto-remove (copy) suffix from new subitem names⁠ 
For dates on new subitems (creation date + offset, parent date + offset, etc.) see  Date & timeline automations⁠ . For per-name creation rules ("when subitem is created and if the name is X…") see  Smart rules & by-name automations⁠ .
