How to Add More Than Three Page Sublevels in OneNote
Question details
The user needs to create a deeper page organization by adding more than three sublevels in their notebook.

- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Structuring highly detailed or complex notes that require extensive categorization and deep hierarchical nesting.
- Observed behavior
- OneNote currently restricts the page hierarchy to a strict maximum of three levels (Page, Subpage, and Sub-subpage), preventing any further page demotion.
Be aware that OneNote has a hardcoded architectural limit of three page levels. To achieve deeper organization, you will need to utilize Section Groups or submit official feedback to Microsoft for future updates.
Submit a Feature Request to Microsoft
Since the three-level limit cannot be bypassed within the app's settings, the official recommendation is to submit a feature request to the Microsoft product team.
Microsoft actively monitors user feedback to plan future updates. Requesting a fourth or fifth sublevel helps the development team understand the demand for deeper page organization.
Open your Microsoft OneNote application and click on the 'Help' tab located in the top ribbon.
Click on 'Feedback' (or 'Suggest a Feature' depending on your version) to launch the Microsoft feedback portal.
Explain that you need more than three page sublevels for your workflow and describe how it would improve your note organization, then click 'Submit'.

Use Section Groups for Deeper Hierarchy
While you cannot add more page sublevels, you can group your notebook sections to create additional structural tiers above the page level.
Looking for Advanced Document Structuring?
If simple note-taking apps restrict your organizational needs, consider switching to a full-featured word processor. WPS Office is a highly compatible, free alternative that allows for unlimited multi-level lists, comprehensive outline views, and advanced document structuring to manage complex information without strict nesting limits.
- 1. Download WPS Office: Visit the official WPS website and download the free installer for your operating system.
- 2. Install and Launch: Run the setup file, follow the prompts, and open WPS Office once the installation finishes.
- 3. Start Creating: Open WPS Writer to draft highly structured, multi-level documents that easily surpass standard note app limitations.

Frequently Asked Questions
What are the specific page levels currently supported in OneNote?
OneNote supports exactly three levels of page hierarchy: a primary 'Page', a 'Subpage' nested beneath it, and a 'Sub-subpage' nested under the subpage.
Can third-party add-ins help me add a fourth sublevel?
No. While add-ins like Onetastic provide advanced macro features and sorting capabilities, they cannot alter the fundamental hierarchy structure hardcoded into OneNote.
How do I promote or demote a page in my notebook?
Right-click the page tab in your page list and select 'Make Subpage' to demote it. To reverse this, right-click it again and select 'Promote Subpage'.
Is there a limit to how many subpages I can create at one level?
No, while the horizontal depth is restricted to three levels, you can have a virtually unlimited number of subpages or sub-subpages running vertically down your list.
