Hiding Collections in Main Menu in the Simple Theme

[tinabluemoon]

I am using the Simple Theme and need to hide menu items when the collection is empty. I found the menu code in the sidebar.liquid. Can someone please help me with how to adjust the code to hide empty collections from the main menu? Any help is appreciated!
