Convert task to subtask

Hello there :slight_smile:

So in a project list view type its easy to drag a task to another task to convert it as a subtask of the second one, as explained by @Aisling_Grogan and in

But how about doing the same in a project board view type?
Can anyone help me here?

Many thanks


Hi @Ricardo_Ferreira - the equivalent subtask functionality does not exist in boards view right now. However, we hope to expand boards functionality very soon.


I’m wondering what’s your scale for “soon”…
I’m here at this thread because can’t move a task under another one in board view… and can’t change the view to list.
I tried @Peter3 's solution from above and that works - but that’s a workaround. I have some itching when I need to click more than should (might be personal… that’s my user-feedback).
Keep up… and publish, please, a roadmap instead of ‘soonifying’ the customer support threads :slight_smile:

Hey there @Geza_Molnar. Thanks for your thoughts! If you’d like to see this as a feature I suggest you add to an existing relevant thread in the #productfeedback category or you can feel free to create a new one. :slight_smile:

Hi, i think this could also be usefull to “convert section to subtask”

So, moving a section should carry all it tasks…
This is also true when sorting sections… theres no way to select or move al tasks bellow that section…



Here is one

and two

Keep up!

It will be great to select more than just one by one the tasks to drag them into another task. I tried selecting to tasks and I just had the screen “Yo selected 2 Tasks” at mi right and not the main task where I wanted to move them.

This is not working for me. When I attempt to drag the task into the other, I get a error symbol. It will only let me move it above or below. I have no idea what I am doing wrong. This is so frustrating as I have spent hours setting up my Asana to transition from paper planners and now I realize I need to condense and use more sub-tasks. I have so many that I need to move. If you could assist me with this, I would be very grateful. Thanks!

Hi @Jessica_Edson-SImmon - we’ll be happy to help! You should be able to easily convert subtasks to tasks via drag and drop. Could you please provide a screenshot of the error message you’re seeing?

Hi, Alexis! I must have misunderstood the previous post. What I am attempting to do is convert a task to a subtask. Is this possible?

@Jessica_Edson-SImmon Yes this is possible. It’s just not ideal. I just finished doing this for about 50 tasks and it didn’t take too long but way longer than it should.

You can NOT select multiple tasks and then turn them into subtasks in the same way you can select multiple subtasks and drag them over to become tasks.

With subtasks you must do the following:

  • Have the Destination Task and the Eventual Subtasks in same project (preferably near each other)
  • Select the Destination Task with mouse click bringing up the task on right hand side
  • Hover over ONE Eventual Subtask and click/hold on the drag icon
  • Drag this Eventual Subtask over to the right hand side Destination Task BELOW the Description box
    • This is important: IT MUST BE RIGHT ON THE LINE under the Description box if no subtasks exists, otherwise you will see the red error symbol
    • If subtasks already exist then just drag it amongst them where you need it

The reason you can’t multi-drag tasks into a Destination Task is that by the nature of Asana this brings up a combined task view on the right hand side, replacing your Destination Task view.

This is “working as intended”. The only way to fix this would be for them to add a menu option in the task view that says “add as subtask” and lets you choose what task to add the multi-selected tasks to.


thanks for that detailed description. Very helpful as its exactly what i was trying to do!


Hmmm. This is not in ‘Boards’ view, is it? At least I can’t figure out how to select the Destination Task AND keep it visible while I then selected the Eventual Subtask to be dragged and dropped.

Unfortunately, this would need to be done in a list view. The good news is that you’re not stuck…

You will need to do an advanced search, targeting only that board project. This brings the tasks up in a list view. Yay! Now you can highlight them all and either assign them to yourself to edit in my tasks OR add (multi-home) them to a blank temporary list project. Then you can do the above method (assuming the tasks and subtasks are on the same board).

Note: Thanks to @Kevin_Leggett for testing this, but you can NOT drag tasks in advanced search mode so you MUST add it to another project or your task list.

If the tasks aren’t on the same board or you don’t have Advanced Search capabilities (paid version) do the following:
Create a new list project to temporarily hold tasks. Add (multi-home) the board tasks that you need one at a time to a temp list project as you can’t multi-select tasks on a board. Now the tasks are in two projects. At this point you can drag items into the tasks as noted in previous posts from the temp list project. Once finished you can simply remove those tasks from the temp list project (keeping them in the board project) and now you have Board tasks with the subtasks you needed. Remember you can select multiple tasks in the list view to remove them all at once from the temp list project.

Not ideal… but it should work.

As a side note, this is why I ONLY use board tasks as project overview boards where the board tasks are multihomed “information” tasks for various other projects that I move between “stages” (columns) on the board project but allow me to easily see custom fields for both projects and click into the parent project. Boards are good for very specific use cases… if you want to use boards for everything you do… just use Trello. The power of Asana is in the list view. They could add features of the list to the boards at some point, but the nature of boards make it hard to do what you can do in list view… that’s not Asana’s fault but merely a logistics/UI/UX problem inherent with boards and why we left Trello…

I was unable to drag and drop the tasks under the advanced search/saved search report results… however was able to use the ‘my tasks’ sorted by project (after assigning tasks i wanted to move to myself) to get the same result (open the target task - appears in right pane, then i was able to drag other tasks as subtasks).

Hi Matthew. Thanks so much for this detailed and hugely helpful response. I’ll try what you suggest, but take my time at it!

You’re correct, you can’t drag from advanced search. :frowning: Your solution works if none of the tasks were already assigned to you. I guess you could sort them by project in your my tasks and go that route. But rather than junk up your My Tasks, its nearly as simple to just make a blank project and multi-home them to that.

The beauty of the advanced search is that you can multi-select tasks that are stuck on boards.

I’ve updated my instructions above. Thanks for the feedback!

Thanks Matthew, I agree blank project is the way to go. It was getting messy pretty quickly so I tried the blank project which was much easier. I hadn’t spread tasks across multiple projects before and now I suspect I will do it all the time, especially with my board projects.

Hello! To make one task a subtask for another task, I need to drag it to this task. In this case, both tasks should be in the same project. Sometimes tasks can be on different projects.
It would be great if it was possible to assign a parent task to the task. For example, through the menu item Set parent task.
