The Child Page List template automatically adds a bulleted list of child and grandchild pages.
The image below is an example of the Child List template result.
To use the Child List template:
Create a new page; give it a name.
Place your cursor where you want the bulleted list to appear. You can choose to leave the page blank, or add content to the page and position your cursor above or below the content.
Publish or Update the page.
