Hi katelwilliams,
Tasks and subtasks will always show in every view, but in any view they'll be collected under a parent task if both show in the same view. In your example, if you tag a task and its subtask with the same tag, the subtask will show inside the task.

Hope this helps, but let us know if you're seeing anything else!

Well, if it only shows when you click on the parent task it isn't really showing in any view. I'm currently looking for a new task management system, so I'm trying out RTM. I like a lot of what I see, but the subtasks seem very awkward.
BUT - I see that you can drag a subtask into the main list pretty easily -- would the subtask keep the same tags and other attributes as its ex-parent task? That could be a decent work around. Most parent tasks are actually projects, so if you use a tag for the project name, the subtasks could be manually moved (in bulk, hopefully?) to the main view in a weekly review -- that might be adequate for some users.
I will also note that it's a bit frustrating not to have access to a trial version of Pro. I'm willing to pay for it if it works for me, difficult to determine this from reading comments/forum etc. Thanks

Hi welred,
Dragging a subtask to the main list separates it from its parent task; it’s now its own task without the connection to the other task.

We don’t currently offer trials for Pro, but we’re happy to Posted 8 years ago

Hi rlieving,
We see your feedback in that Ideas Forum topic, thanks!
