Add a level of table of contents

The table of contents can contain up to 9 levels of headings. By default, it consists of three levels. The first level of the table of contents is the headings to which the Heading 1 style is applied, the second level is the headings to which the Heading 2 style is applied, and the third level is the headings to which the Heading 3 style is applied.

In general, a table of contents includes no more than five levels of headings. When you add the fourth and fifth levels of the table of contents, the preset Heading 4 and Heading 5 styles are automatically selected for them, respectively.

If you need to add more than five levels of headings to your table of contents, create styles manually and apply them to the desired headings. Then add the table of contents levels that will be generated from these headings.

To add a level of table of contents, follow these steps:

1.Open the Edit table of contents window in one of the following ways:

•Left-click the table of contents and on the Home tab, in the Contents group, click  Edit.

•Right-click the table of contents and run the Edit table of contents command from the context menu.

2.In the Edit table of contents window, click  New level. The list of levels will display a line for the new table of contents level.

3.Select from the drop-down list the heading style from which you want this table of contents level to be generated, or leave the default style selected.

4.To close the Edit table of contents window, click outside the window or click the button in its title bar.
