This plugin will allow you to display the content of subpages as expandable links.
Simply add [subpages_expand] to any parent page. The titles of each of the subpages will be displayed there as clickable links. When the user clicks the link, it will expand, displaying the content of that child page.
Clicking the title again will collapse the content.
