Help with Splide in Nested Collection List

Hey guys, I’m trying to implement a splide in a nested collection list.

I have two collections; Brands and Items where Items has a reference field that points to Brands thereby establishing a one-to-many relationship between Brands and Items.

Now, I want to implement something like the screenshot below

Here Nivea and Oraimo represent my brands which is the source of the parent collection list then a Splide is implemented in the child collection list where Items is the source so I can display a carousel of items related to each brand.

This is a client project so I’m not sure if I should share the read-only link but I’d appreciate any help I can get.
