How can I set a task dependency?


How can I set a task to be dependent on completion of another a task in a different project, i.e. It is not possible to mark the task complete until the task on which it is dependent is marked complete?

unfortunately, that's not possible right now, but we may consider adding such feature in the future. You're welcome to add your vote for these requests in our Votebox:

For now, as a workaround, you could set sub-tasks below a task that represents a bigger goal, however, it will be possible to complete the main task anytime which will complete the whole structure, but you'll also be able to check off single sub-tasks.

Best regards,

Thank you; this was helpful. I had searched but not found the proposals you referenced, so thank you for that information also.

The votebox is closed, but I would love to see this feature. It's key to anyone using GTD, which sounds like a very large percent of your user base. Thanks!

+1 from me

The workaround with Subtasks is ok, but one should see in every subtask to which parent task it belongs.

Another +1.

For example, I would love to have the ability to set subtasks to be sequential, so that tasks 2–3 are not visible until task 1 is complete.

+1 !!

I used this all the time with omnifocus, so it would be nice to have this feature.

+1 I really need this feature. Most of my tasks are dependent.

This is getting more and more important for me.

One of my jobs is to send newsletters. I set up a project with all tasks in it as template. The problem is, that most of these tasks have dependencies e.g. I first have to do the brainstorming, then collect information about the newsletter content, then update the addresses, and so one.

Now I can load the project template, which is a nice functionallity. But then I have to set all the due dates for each of the about 15 tasks manually.

I have many projects / tasks like these. More and more every few months.

I really love Todoist. And I hope, these feature will be implemented soon, before it becomes a showstopper for me.

Regards, Paddy

I'm seriously considering moving back to OmniFocus. I liked ToDoist bc of better Gmail integration, but this feature, along with programmatically labeling/identifying Next Actions (as per GTD method) are so important and my time spent managing Todoist is getting way out of hand.

@Staff, could you please let me know if there anything in the works for dependencies and automatically identifying Next Actions? This guy built something, but it requires knowledge of python, which I don't have. If this could be implemented into the product, that would be great!

Really need dependencies and how to easily see the parent task to which a child is associated.

I found this site while googling Todoist task dependent upon completion of another task. This feature would be one of the best points about Todoist.

The question is over 2 years old but the issue is still standing - is it really that low on the work stack?
