How do i reduce this to one loop?

Hello guys,

I have the following code that i would like to optimize by reducing the 2 loops to a single one.

Problem is that there’s some specific code i only need run once(the nav and section elements). Those need to be outside the loop, so i’m forced to close the nav loop before i can begin the section loop.

Any help would be greatly appeciated.
