There are many ways to set up a directory. Let me introduce one. Open the document first.
Then click View, and then click Outline View. As shown in the figure.
On the new page, we can see some points on the left. Click on the content you want to set as a directory, and then set the level. After setting them in turn, click Close Outliner. As shown in the figure.
Then click Reference, Directory and Auto Directory 1, and the directory is automatically inserted.
