How to create subactivities

When a card’s work is too large, the team often breaks the steps in a spreadsheet, a notepad, or a chat thread. Then nobody who opens the activity in Rabbiit sees what is still left — only a generic title.

Subactivities exist so those steps live inside the parent activity. You create them, expand or collapse them in the list, and see the count in the list and on the board. The estimate adds up the children on the parent card: “how much is left” stops being a loose number.

This is team work management, not a feature only for people who log hours. Whoever executes marks the step; whoever coordinates sees the set without opening another tool.

Who it is for

Activities list, where you create subtasksActivities list, where you create subtasks Project member (who executes) — breaks “build the website” into “layout, content, sign-off” on the same card. There is no need to create three parent activities just to stay organized.

Project manager — sees in the list and on the kanban which cards already have children and whether the parent’s progress follows the children. Avoids chasing a card that still has five steps hidden in someone’s head.

Administrator / project manager — decides whether the member can create and edit subactivities in the project activity permission (edit includes title, description, and the Subtasks block).

Whoever only logs hours — can keep logging on the parent activity. The subactivity organizes the work; time entry follows the project habit (parent or, if the team agrees, the detail you use).

Where to find it

Projects > Activities — open the parent activity (click the row or the ⋮ menu → Open details). In the modal, the block is Subtasks. On the board (kanban) the card shows how many subactivities exist.

How to create and follow up

Activity modal, in the Subtasks block, where you add childrenActivity modal, in the Subtasks block, where you add children

  1. Open the project and the Activities tab (list or board).
  2. Open the activity that is too large for a single step — the detail opens in the modal.
  3. In the Subtasks block, add the row and type the name (“send the proposal”, not “ok”).
  4. Expand or collapse in the list as you work.
  5. Fill in the estimate on each step that has a size. The parent shows the sum of the children (plus the parent’s own estimate, if any). Details are in hour estimates on activities.

Children are unlimited: each subactivity can have its own. In the list and in the modal you see two levels at a time — the activity you opened and its children. The next level appears when you open the child (and so on, with no cap).

To change the level, drag the row. Dropping on a root activity keeps the list level. Dropping on the children section makes it a child of that parent. You cannot move an activity into its own branch.

Do not duplicate the same work as a sibling activity “just to appear on the board”. If it is a step of a deliverable, it is a child.

When to use — and when not to

Use when the card has a clear sequence (discovery → execution → review) or when several people touch the same deliverable and need to see what is still open.

Do not use for work categories that repeat across every project (Consulting, Development). That is a catalog task, not a subactivity.

Do not use for conversation and files. Comments and attachments stay on the card — see attachments and comments on activities.

What gets easier

The detail of what is still left stops living in another channel. Anyone who joins the project mid-week understands the card without asking in chat. The board shows the volume of steps, not just an optimistic title.
