Choose related products from same collection & enabling swipe on mobile

[Tolunay]

Hey guys, do you know a way to put products from the same collection as the product page on the related products section on my product page. And also enabling swipe on mobile for this section just like the featured collection on my page.

I have set up the store myself with the dawn theme and i have added some coding. I can't seem to edit the related products section to enable swipe on mobile.
And it also doesn't show products related to the product on the product page, so I was thinking maybe someone could help with a code so I can add the only products from the same collection as the product selected.
I haven't found anything in the normal store setup
