Tasks and subtasks
Create tasks, fill in their details, break them into subtasks, assign and schedule them, show them in several projects, and complete them.
Last reviewed October 11, 2026
Tasks are the pieces of work on a project board. This article covers creating a task, its fields, subtasks, assigning and scheduling, showing a task in more than one project, and completing it.
What this page helps you do
- Create a task and fill in its details.
- Break a task into subtasks with their own owners and dates.
- Assign teammates and set a due date.
- Show one task on several project boards.
- Move and complete tasks, and use the right-click menu.
You'll start from a project board (Projects in the sidebar, then click a project card).
Create a task
- Click the ⊕ in a column header (every column except Done), or New Task in the board header.
- The Create a new task sheet opens. Type a title where it says "Task title".
- Fill in anything else you already know: description, tags, assignees, due date, priority, Repeat, other projects.
- Click Create task.
Helpful details
- Key areas: the title, the description editor, and a grid with tags, assignees, due date, priority, Repeat and Show this task in other projects.
- What you can do: only the title is required. Everything else can be added later from the task sheet.
- Good to know: the ⊕ puts the task in that column. New Task puts it in To Do.
The task sheet
Click a task card to open its sheet. Edits are not saved until you click Save.
Helpful details
- Key areas: the title (click it to edit), the description, Tags, Assign to, Due date, Priority, Repeat, Show this task in other projects, the Save button, then the Subtasks and Comments tabs.
- What you can do: the description takes Markdown, up to 1000 characters; click Edit to change it. Priority is No Priority, Low, Medium, High or Urgent. Tags lets you pick existing tags or create one; tags are shared by the whole team.
- Good to know: there is no status field and no attachments. A task's column is where it sits on the board; move it by dragging the card. Paste links in the description or a comment instead of attaching files.
Subtasks
Open a task and stay on the Subtasks tab.
- Type in "Add a subtask..." and click Add (or press Enter).
- Tick a subtask's checkbox when it is done.
- Use the small controls on each subtask to give it its own Assignees and its own due date.
- The ⋮ menu on a subtask has Convert to task and Delete subtask.
Helpful details
- Key areas: the composer row, one line per subtask with a checkbox, text, due date and assignee pickers, and the ⋮ menu.
- What you can do: Convert to task opens Create a new task with the subtask's text as the title. Once you click Create task, the new task lands in To Do and the subtask is removed from the parent.
- Good to know: the Subtasks tab shows how many subtasks are still open, and cards on the board show a subtask count. Subtasks cannot be dragged to reorder. Use subtasks for short steps inside one piece of work, and separate tasks when each step needs its own description or comments.
Assign a task
In the task sheet, open Assign to and tick one or more teammates, then click Save.
Helpful details
- Key areas: the Assign to picker, which lists everyone in the team.
- What you can do: assign several people when the work is shared. Remove someone by unticking them.
- Good to know: each new assignee gets an in-app notification and an email ("Task assignments" in their notification settings). Their tasks show up under My Tasks in All Tasks and on their dashboard.
Set a due date
In the task sheet, click Due date and pick a day, then click Save.
Helpful details
- Key areas: the Due date picker. Due dates are whole days, with no time of day.
- What you can do: a task with a due date shows on the Calendar tab, in the All Tasks list sorted by Deadline, and on the task Timeline.
- Good to know: when the day has passed, the date turns red on the card. Nothing else changes: the task stays where it is until you move or complete it.
Due dates and time zones
A due date is the calendar day you picked, saved as midnight in your own time zone. Boardssey reads your time zone from your browser; there is no setting to change.
Helpful details
- Key areas: every place that prints a due date or decides "overdue", "today" or "this week": boards, All Tasks, the Calendar, the Timeline and the dashboard.
- What you can do: nothing to set up. Each person sees dates in their own zone, and a task turns overdue at their local midnight.
- Good to know: teammates many hours apart can see the same due date one day apart. A date set in Tokyo for Monday can show as Sunday for a teammate in Los Angeles. Milestones work differently: a milestone date is the same day for everyone (see Plan key dates with Milestones).
Show a task in other projects
A task belongs to the board it was created on (its primary project), but you can also show it on other boards of your team.
- Open the task sheet.
- Under Show this task in other projects, pick the other projects ("Link to other projects...").
- Click Save.
Helpful details
- Key areas: the project picker. The primary project is marked "(primary)" and cannot be removed.
- What you can do: the task appears on each linked board with an Also in badge. Editing it anywhere edits the same task.
- Good to know: on another board, the task is only visible to people who can open its primary project. If the primary project is private, teammates outside it will not see the task on the linked boards either.
Move and complete tasks
Drag a card to another column to move it. To finish a task, tick the checkbox on its card, pick Mark Complete from the right-click menu, or drag it into Done.
Helpful details
- Key areas: the checkbox at the left of each card, and the right-click menu: Mark Complete, Send Reminder, Duplicate Task, Delete task.
- What you can do: Send Reminder emails every assignee who has "Task reminders" on in their notification settings; it is greyed out when the task has no assignee. Duplicate Task makes a copy named "(Copy)" in the same column, with the subtasks, tags, assignees, due date and repeat settings.
- Good to know: a completed task always goes to Done, whichever column it was in. Drag it out of Done to reopen it. Completing a repeating task also creates its next occurrence (see Make a task repeat).
Tips & common questions
Do tasks belong to a game? A task belongs to a project. A game project's tasks sit in that game's row on the task Timeline and count toward the game on the dashboard. A team project's tasks have no game.
Can a task be on more than one board? Yes, with Show this task in other projects. It stays one task with one primary project.
What is the difference between a tag and a column? A column is where the task is in your workflow. A tag is a label (art, blocked, rules). A task sits in one column and can carry many tags. Tags are shared across every project of the team.
Can I make a task repeat? Yes. Set Repeat in the task sheet. See Make a task repeat.
Can I lock a task so others cannot edit it? No. Who can edit a task follows who can open the project. See Control who can see a project.
Where do completed tasks go? To Done. They stay there until you delete them, and they are not shown in All Tasks or the Calendar.
