How to Fix OneNote Subpage Option Greyed Out
Question details
Users are unable to use the Make Subpage feature in Microsoft OneNote because the option is greyed out or completely unavailable.

- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Attempting to organize notebook sections by creating a nested subpage hierarchy.
- Observed behavior
- The Make Subpage option in the right-click context menu is greyed out and unclickable when a specific page sorting order is actively applied to the section.
Verify that you have editing permissions for the current OneNote notebook and check the top of your page list to see if any automatic sorting filter is actively enabled.
Change the Page Sorting Option to None
Removing the active date or alphabetical sort in the section will instantly restore the ability to create subpages.
The primary cause of this issue is OneNote's page sorting functionality. When pages in a section are sorted by 'Date Created', 'Date Modified', or alphabetically, OneNote enforces a strict list order. Because subpages rely on a custom manual hierarchy, they conflict with automatic sorting rules. You must disable the sort to organize pages manually.
Open the affected section in Microsoft OneNote. At the top of your page list on the right or left pane, click the sorting icon (usually depicted as a small drop-down arrow next to the current sort criteria).
In the drop-down menu that appears, select the 'None' option to disable any active sorting by date or alphabetical order.
Right-click the page you wish to demote in the page list. The 'Make Subpage' option will now be fully clickable. Select it to nest the page under the one directly above it.

Frequently Asked Questions
Why does sorting pages disable the subpage feature in OneNote?
When an automatic sort (like Date Created or Alphabetical) is applied, OneNote locks the page order to strictly follow that rule. Because making a subpage requires manually nesting a page under another regardless of its date or name, it conflicts with the automatic sort, prompting OneNote to disable the feature.
Can I sort pages while keeping my subpages grouped together?
Unfortunately, no. You cannot simultaneously apply an automatic page sort and maintain a custom subpage hierarchy in OneNote. You must set the sorting option to 'None' to use subpages.
How do I turn a subpage back into a regular page?
Ensure your page sorting is still set to 'None'. Then, right-click the subpage in your page list and select 'Promote Subpage'. Alternatively, you can click and drag the subpage tab to the left until it aligns with the main pages.
