Dependencies
Dependencies express order between tasks: when one task can only start after another is finished. You add the prerequisites on the task that depends on them, and while any prerequisite is still open that task shows as blocked. When the prerequisites are done, it unblocks on its own. This page shows how to add a dependency, what blocked means, and where dependencies appear.
Each task carries a "Depends on" list — its prerequisites. The direction is always the same: you open the task that has to wait and point it at the tasks that must come first. There is no separate "blocks" field to fill in; a task being a prerequisite is just the other side of the same link.
Add a dependency
Dependencies live in the card details, in the "Depends on" section. Only tasks from the same project can be chosen — each project is independent.
- 1Open the task that has to wait for another (the dependent task).
- 2Find the "Depends on" section in the card details.
- 3Use the "Add dependency" picker to add a prerequisite task; repeat to add more than one.
- 4Each prerequisite appears as a chip; remove one with the x on the chip.
Subtasks never appear as candidates because a parent waiting on its own child could never be finished. Subtasks themselves can be nested — a subtask can have subtasks of its own, up to 6 levels deep.
Blocked tasks
A task is blocked while at least one of its prerequisites is not done yet. As soon as every prerequisite reaches the done status, the task unblocks automatically — there is nothing to toggle by hand.
A blocked task shows a lock badge labelled "Blocked". Hover it to see "Blocked by" followed by the prerequisites still holding it up, so you know exactly what to finish first.
You can also focus on what is stuck: the "Filters" panel includes a "Blocked" filter, so you can narrow any view down to just the blocked tasks. See the "Views" page for how views and filters work.
See dependencies
The Timeline view is where the chain becomes visual. Tasks are drawn as bars over time, and dependencies are shown as arrows pointing from each prerequisite to the task that waits on it, so you can read the whole sequence at a glance.
In the Timeline, a blocked task also carries a small lock icon next to its name, matching the blocked badge you see on the task cards. See the "Task cards" page for the card details where dependencies are edited.
