Hi all,

We are reviewing this request at the moment and will provide a follow-up in a few months time. We understand that especially with the recent release of subtasks support in backlog, there is a higher interest for subtasks to be made visible in Timeline.

At the time being, as some of you have noted in the comments below - you can use Timeline inside Plans for this purpose. Plans can take a single or multiple projects, boards, and filters as their issue sources and display the relevant Jira issues, including subtasks.

Plans are available for Jira Premium (https://www.atlassian.com/software/jira/premium) . You can learn more about Plans here: https://www.atlassian.com/software/jira/guides/advanced-roadmaps/overview#what-is-advanced-planning . Just head over to the “Plans” menu item on top navigation in Jira to give it a go.

Thank you for your patience on this request.

Regards,

Irene Ongkowidjaja

Senior Product Manager

Thank you for your valuable feedback. We hear your concerns.

_After the recent release of displaying story/task level issues on the timeline in Kanban projects, we can now assess this request appropriately. https://community.atlassian.com/t5/Jira-Software-articles/What-s-new-in-the-Roadmap-view-I-m-so-glad-you-asked/ba-p/2077594_

When commenting or voting on this ticket, we are always interested to know the "why" behind your team's need for the ability to drill down or plan on this granular level with sub-tasks, or what context you or stakeholders are missing by not seeing any information related to subtasks. 

_We appreciate your insights - and if you would like to chat in detail about this,  feel free to reach out to the team directly: jira-cloud-roadmaps@atlassian.com

Thanks, 
Rathesh Richards, Product Manager, Jira Software Cloud_
