Child items are used in Teamhood to break down larger items into smaller, actionable tasks for the team. Teamhood supports unlimited levels of subtasks, which can be visualized in Gantt, List, and Kanban (2 levels) views.
Here is more on child item management.
To create child items, locate the child item icon.
In Kanban view, this icon appears when you hover over an item card. In List and Gantt views, the icon appears when you hover over the item’s name.

You can also add child items by opening the item details and clicking on ‘Add Child Item’ in the Item Relations section.

Teamhood allows you to create as many child item levels, as you need. There is no limit. To see all levels, open the List or Gantt views and expand the chosen item. Kanban view visualizes only the first 2 levels.

To create further child items, use the same steps described in the above section.
Child items in Teamhood have the same properties as parent items. You can assign team members, add watchers, leave descriptions, comments, attachments, etc.
You can read more about Item properties here.

Moreover, child item schedule information can be used to aggregate information for the parent item. For example, if you set schedules for the child items, but there is no schedule set for the parent item, the schedule for the parent item will be set automatically according to the child item schedule.
Here are all the child item field types that aggregate for the parent item:
You can later edit the parent item schedule per your needs.
When calculating parent items’ progress, Teamhood considers that task durations vary, and completing a short task is not equivalent to finishing a longer one. To calculate the aggregated progress of the parent item, we consider:
The formula is:
(total completed days) / (total duration) *100%

Total completed days in the same order:
4+2+0+0 = 6
Total duration in the same order:
4+4+2+1= 11
Aggregated % of parent item/milestone:
6/11*100% = 55%
Teamhood allows you to convert child items into parent items. To do so, open the child item details and click on ‘Convert to Parent’ in the quick action menu.

The converted child item will be placed in the same location as the parent item.

You can also convert child items to parent items by using drag & drop. Simply drag and drop the selected child item next to the parent item.

The conversion works both ways. As well as promoting a child item to a standalone parent, you can take any Kanban item and make it a child of another card, keeping its progress and history intact.
Use it when a task raised on its own turns out to belong to a larger work package — it keeps related work grouped without anyone having to recreate the item.
Automations understand parent and child relationships, which removes a lot of the manual upkeep in structured projects:
