Replaces the Genesis Secondary Menu with a dynamic listing of the current section’s subpages. You must be using the Genesis Theme Framework, and your child theme must support the Secondary Menu theme location.
Simply activate the plugin, then go to a page with subpages. It should list all the subpages in the secondary menu. Navigating to a subpage will keep the same menu (it lists all subpages of top level page, not current page).
If you go to Appearance > Menus, it will show the Secondary Menu location as currently set to “Genesis Subpages”.
Want a similar listing in your sidebar? Use my <a href="https://wordpress.org/plugins/be-subpages-widget/" rel="ugc">BE Subpages Widget</a> plugin

Genesis Subpages as Secondary Menu

It just works as required. Brilliant and simple solution to solving a bit of programming.
Thanks



Brilliant solution

Elegant solution. Once implemented it's hands off for the user - new child pages are handled automatically with no need to update the menu.

Very handy
