Word can display expand/collapse arrows next to paragraphs that use heading outline levels. If you want to remove that behavior from particular text, change the paragraph so it is no longer treated as a heading. Simply hiding the arrow without changing the document structure is not generally the intended control.
How to Remove Expand and Collapse from Text in Word
Step 1: Select the heading
Click in the paragraph that shows the expand/collapse control, or select the affected headings.
Step 2: Open the Home tab
Select Home and look at the Styles group.
Step 3: Apply a non-heading style
If the paragraph does not need to be a heading, apply Normal or another appropriate body-text style. The expand/collapse behavior is tied to the paragraph’s outline level.
Step 4: Adjust formatting if necessary
Restyle the paragraph to preserve the appearance you want without assigning it a heading outline level.
Keep Real Headings as Headings
Do not remove heading structure merely because you dislike the expand/collapse arrow. Proper heading styles help organize long documents, support the Navigation Pane, improve accessibility, and can be used to build a table of contents.
If Custom Formatting Is Causing the Behavior
A paragraph can have an outline level even when it does not visibly use a built-in Heading style. Open the Paragraph dialog and review the outline level. Change it to body text only when the paragraph is genuinely not a heading.
Additional Information
Collapsing a heading does not normally delete its content; it changes how the document is displayed while editing. If your concern is what readers see in a PDF or printed copy, check the exported or printed result before restructuring the document.
