This widget will dynamically list a section’s subpages. When on a page, it will find the section’s top level page and list its children.
It can also include the current page’s subpages in listing.
You can customize the listing with the following filters: 
be_subpages_widget_args – modifies the arguments passed to wp_list_pages 
be_subpages_widget_display_override – determine when the widget is displayed 
be_subpages_widget_override_post – change the current post 
be_subpages_widget_parents – customize the hierarchy used in querying subpages 
be_subpages_widget_title – customize the widget title 
be_subpages_page_title – customize the page title 
be_subpages_widget_class – customize the classes applied to pages

BE Subpages Widget

Prefect plugin.  I was using a custom-coded shortcode to do this, but was having trouble getting the children/grandchildren page lists to appear outside of the parent list's li element.  The default in this plugin to not nest subpages is perfect for the style I need to set up.  Thanks!
