Actually there is a slightly simpler way to make next or previous actions then sabanna suggests.
In my case I reused the reference field linking to itself, creating kind of a loop.
- First you need to create a reference field in the same collection. Name it Next.
- Link the reference to it self.
- Save the collection.
- Go to the Editor and create a button, name it “Next”. In the Link settings make sure to click on the “A collection detail page” and to pick from the dropdown “references > next”.
- Go back to collections and in the items list and pick one item.
- In the “Next” field select the item that should appear next as the “Next” button triggered. (Repeat for each item)
Same way can be created previous button.
