Question details

Users are experiencing an issue where colored section tabs in OneNote are stacking or hiding inappropriately, even when there is sufficient horizontal screen space.

Product: Microsoft OneNote
Device & OS: Windows 11
Scenario: Organizing and navigating notebooks using horizontal colored section tabs at the top of the OneNote application.
Observed behavior: Section tabs unexpectedly stack or disappear due to forced spacing near the Search Notebooks box. Widening the application window reveals the hidden sections.

Before you start

Before making changes or updating your software, verify that your current OneNote notebooks are fully synced to your Microsoft account to prevent any accidental data loss.

Widen the Window and Update OneNote

Since this is a confirmed layout bug related to forced spacing near the Search box, manually widening the window is the quickest temporary workaround while waiting for an official patch.

Recent updates to OneNote introduced a design change that forces extra spacing between the section tabs and the Search Notebooks box. This causes tabs to collapse or stack even when the window appears wide enough to hold them all.

Maximize or Widen the Window

Click and drag the left or right edges of the OneNote application window to make it wider, or simply click the Maximize button in the top right corner. This extra space will force the hidden section tabs to reappear.

Check for Office Updates

Microsoft frequently patches layout bugs. Go to File > Account > Update Options and click 'Update Now' to ensure you have the latest version of OneNote installed.

Submit Feedback to Microsoft

If the issue persists, go to Help > Feedback within OneNote to report the bug directly to Microsoft. Be sure to include your Windows version and a screenshot of the layout issue.

Alternative View: If horizontal space remains an issue, consider switching to vertical tabs by going to View > Tabs Layout and selecting 'Vertical Tabs'.
