How to Fix Missing Expand and Collapse Heading Controls in Word for Mac
Question details
The user is unable to see or use the expand and collapse triangles next to heading styles in Microsoft Word.

- Product
- Microsoft Word for Mac
- Device & OS
- Mac
- Scenario
- Organizing and navigating a document using standard Heading 1, Heading 2, and Heading 3 styles.
- Observed behavior
- The headings do not display the small triangle icons needed to collapse or expand sections within the document.
Ensure that you have correctly applied standard heading styles (such as Heading 1 or Heading 2) to your text, as regular paragraph text will never display these outlining controls.
Use Outline View to Collapse and Expand Headings
Since Word for Mac does not support expand/collapse controls in the standard Print Layout view, you must use Outline View to manage and collapse document sections.
The inline expand and collapse feature (the small triangles next to headings) is natively exclusive to the Windows version of Microsoft Word. On macOS, this feature is not supported in the standard layout views.
To achieve the same section-collapsing functionality on a Mac without losing your formatting, you can utilize the built-in Outline View.
Open your document in Microsoft Word for Mac and click on the 'View' tab located in the top ribbon.
Click on the 'Outline' button to switch your document into Outline View.
Use the plus (+) and minus (-) symbols that appear next to your headings, or use the 'Show Level' dropdown menu in the Outlining tab to expand or collapse specific heading levels in bulk.
