Customize mobile menu: all links on one screen

I believe this is a common question repeated, but I have scoured the answers for code, and I am not seeing it, specifically. 

For subpages contained within a folder, I would like the user to NOT have to click that arrow and get another overlay just for those subsection links. Images included on what it is by default and what I want to do instead. Version 7.1

Thanks in advance!!

This is Squarespaces' basic layout of header navigators on mobile.

If you want to apply the collapse menu, we need to use javascript to create a new layout HTML and set the appropriate style.

Javascript is only available on Business Plan or above ones.
