Hide Submenu When No Inventory

[Jason021]

Hello,

I'm currently using the Dawn 14.0 theme. The menu that I'm using is the mega menu. 

header-mega-menu.liquid

Inside the menu, on my site, I'd like for the grandchildlinks not to be visible if the inventory for the link is 0. I've spent several days learning code and reading on solutions for other themes, or older versions of Dawn, but have had no luck fixing this issue. Below is the entire code for my dawn menu. Please help.
