Final answer:
To disable expand/collapse in Word, you need to switch off the Track Changes feature from the Review tab and use the Reviewing Pane to view changes without expansion. The steps are suitable for managing tracked changes format in a Word document.
Step-by-step explanation:
To disable the expand/collapse feature in Microsoft Word, which is often associated with the tracking of changes or document outlining, you need to address the settings specific to the feature causing the expansion or collapse. It's important to clarify that 'expand/collapse' can refer to different functionalities, such as those found in tracked changes or document outlines. However, seeing as your question appears to be about tracked changes, here are the steps to manage this feature:
Open your Word document and click on the Review tab above the tools ribbon.
To stop tracking changes which cause the text to expand and show revisions, toggle the Track Changes to off in the tools ribbon.
If you want to view all changes without the expand/collapse format, click on Reviewing Pane within the tools ribbon to open a panel displaying all changes.
To navigate to a specific revision, click the revision in this panel without dealing with the expand/collapse feature.
If you're referring to the expand/collapse functionality in the context of document outlines or sections, you might need to look into modifying the headings or the settings in the View tab.
