How to collapse or expand parts of a document?
To make readers read or see only the part they are interested in, this function is very useful. To do this you have to first give heading to your topic as heading 1, heading 2 ….from Home Menu. Once this done a small icon will appear on the corner of the heading, on clicking on this icon it will merge the content and on re-clicking on it, it will expand the content back to its normal place.
Place your cursor in the heading.
On the Home tab, click the arrow in the Paragraph group.
In the Paragraph dialog box, click the checkbox next to Collapsed by default.
