I have a site set up where I am using the Advanced Custom Field nav menu which is pulling in a menu and I can select which menu is on the page. The problem I am having is I don't want to show the entire (100+) pages that are in the menu but only the child pages of the page that I am currently on.

On that page I have a child page navigation plugin in use and below that is the menu I am trying to work with...The reason I am trying to do this is basically because I have pages that I want to be on multiple pages in their navigation and wordpress only lets you set one parent page in the page tree.
