What it does
This plugin allows you to run loops within your WordPress templates where you query for children of the current page.
How it works
The plugin adds an extra argument to the list of arguments supported by query_posts(). The new query argument
"child_of"is used to add a
WHEREto the database query to limit the pages returned to those with a
post_pageequal to the argument provided.
