Question details

The user is unable to find the expand and collapse arrows next to headings in Word for Mac, despite these arrows displaying properly when the same document is opened in Word for the web.

Product: Word for Mac
Device & OS: macOS
Scenario: Viewing or editing a structured document with multiple heading styles that the user wishes to collapse for easier navigation.
Observed behavior: The expand and collapse control arrows do not appear on the document pages while in Print Layout view on the Mac application, preventing the user from collapsing sections inline.

Before you start

Ensure your document sections are correctly formatted using standard Heading styles (such as Heading 1 or Heading 2) or have specific outline levels assigned, as standard paragraph text cannot be collapsed.

Solution 1Recommended

Switch to Outline View in Word for Mac

Since Print Layout view on Mac does not support inline expand and collapse arrows, switching to Outline view is the standard method for collapsing and expanding heading sections.

Unlike Word for Windows or Word for the web, Word for Mac does not display interactive expand/collapse arrows next to headings in the default Print Layout view. To utilize this feature natively, you must change your document view.

Open View Options

Open your document in Word for Mac and navigate to the 'View' tab on the top ribbon.

Select Outline View

Click the 'Outline' button to switch your document from Print Layout to Outline view.

Expand or Collapse Headings

Double-click the plus (+) or minus (-) symbols that appear next to the headings to expand or collapse the nested content under them.

Heading Levels Matter: Content without an assigned outline level or heading style will appear as a flat list and cannot be collapsed.

Solution 2

Use the Navigation Pane for Document Organization

The Navigation Pane provides a sidebar overview of your document's outline, allowing you to expand, collapse, and quickly jump between different heading sections without leaving Print Layout view.

Frequently Asked Questions

Why do expand and collapse arrows show in Word for the web but not Mac?

Word for the web supports inline expand and collapse controls directly within the standard reading layout. However, Microsoft has not implemented this inline feature for the Print Layout view in the desktop version of Word for Mac.

Can I collapse regular text without using heading styles?

No, the expand and collapse functionality relies entirely on the underlying document structure. You must apply a Heading style (like Heading 1) or assign an Outline Level via paragraph settings to the text for it to act as a collapsible section header.

Will my collapsed document sections stay collapsed when I print the document?

In Word for Mac, documents print exactly as they appear in Print Layout view. Because Print Layout does not support visual collapsing, all text sections will be fully expanded when you print or export the file to PDF, regardless of your Outline view settings.
