Displaying subMenus when you open parent menu page

Hi all,
Not quite sure how to explain this one as I am SUPER new to using WP. I got my little food blog up and running within a week and a half and now that I am able to take awesome pictures of my food, I want to be able to fix some of the site backend.

When you hover over a menu item under Recipes, like “Appetizers” I want to be able to not only display the submenu items in the dropdown function but have the whole list either in an index type method or displayed right away without having to select an actual submenu. Is this possible?

Here’s what I mean
https://www.cooklaughlove.com/recipes/appetizers/
It’s completely empty.

Here’s an example of what I’m trying to do:

Any ideas? Mind you, I’m completely new to this, very little to no CSS knowledge. I really don’t know about customizing my site yet and it’s very frustrating! I just want to cook! ??
