We've just released a new feature: Multi-level boards, which allows for a much deeper hierarchy in boards by supporting up to five layers of subitems.
To help you adapt your apps and integrations, we've published a new API guide that covers all the necessary changes.
Key changes for developers to be aware of include:
-
Deeper Hierarchy: Boards can now have up to five levels of subitems(!)
-
Rollup Columns: This new column type can summarize data from child items.
-
New Board Type: Multi-level boards are a new type, separate from classic boards.
-
Simplified Subitem Access: In multi-level boards, all subitems are now accessible.
- Availability timeline (estimated, might be changed):
- August 25: Multi-level boards available for developer acounts
- October 1: Multi-level boards boards API goes GA
- January 1 (2026): Release multi-level boards in 2026-04 (Release Candidate) as an opt-out
Check out the full documentation for a comprehensive breakdown of the API changes, best practices, and code examples to ensure your apps are ready for multi-level boards.
