I'm creating a nav menu using the {{ nav from="/" }} tag which includes a services page. I'm also using a collection which houses the various services. I want to create a dropdown menu that displays the items in the services collection as children of the services page in the nav.

The nav menu and collection are working independently as siblings, but I can't seem to figure out how to display the collection as a child of the "Services" item in the nav. Is there a way to associate a collection with a specific nav item?
