Question details

Users experience section groups collapsing or disappearing from the interface even when there appears to be enough screen space.

Product: OneNote for Microsoft 365
Device & OS: Windows 10
Scenario: Organizing notes with an increasing number of sections and section groups.
Observed behavior: Section groups unexpectedly collapse or become hidden from view as the total number of sections and groups grows, due to layout limitations.

Before you start

Ensure your OneNote app is fully updated to the latest version to rule out any temporary display bugs before adjusting your layout settings.

Solution 1Recommended

Switch to the Vertical Tabs Layout

Changing the layout to vertical tabs bypasses the horizontal space limitations that cause section groups to collapse.

This behavior is a known layout limitation in OneNote when dealing with a large volume of horizontal tabs. Using vertical tabs shifts the hierarchy to a side pane, allowing infinite scrolling and better visibility for complex notebooks.

Open the View Menu

Launch OneNote and click on the 'View' tab located in the top ribbon.

Enable Vertical Tabs

Look for the Tabs Layout options and select 'Vertical Tabs' to move your sections and groups to the left side pane.

Verify Section Visibility

Check the new side pane to ensure all previously collapsed or hidden section groups are now fully visible and expandable.

Layout Updated: Your section groups will now be nested vertically, preventing them from disappearing off-screen.

Frequently Asked Questions

Why do my OneNote section groups disappear on large monitors?

OneNote has a design limitation where the horizontal layout struggles to display a high number of sections and groups, causing them to collapse or disappear regardless of your actual screen size or monitor resolution.

Does reinstalling OneNote fix the collapsing section groups?

No, reinstalling will not resolve this issue because it is a recognized layout behavior rather than a software corruption error. Switching to the Vertical Tabs layout under the View tab is the most effective workaround.

Can I recover section groups that seem to have disappeared?

Yes, your data is not lost. The section groups are simply hidden due to user interface constraints. Switching your view to Vertical Tabs will reveal all your nested sections and groups instantly.
