Can the navigation flyouts don't work with pages?

I’ve recently downloaded the MultiNews theme

I have the primary menu configured which includes a page as the top level nav item and categories as sub-menu items. The parent navigation item is configured as follows;

Dropdown Menu Type: Category Menu
Categories Post Layout: Horizontal

This normally shows a drop down menu with a horizontal fly-out which shows 3 recent posts from that particular category. Is it possible to still allow the fly-outs to work when they are sub-menu items under a page in the navigation?
