How to navigate to specific element within a repeater?

I’ve already posted a detailed example for such a question (you can try search the forum).
Basically you should add to the button link URL:

 ?id=the_database_id_of_the_specific_item

Then on the second page, use wixLocation.query.id to get the desired id, then use reapeater.forItems([itemId], ($item)…
and inside the block put $item(#detailsContainer).scrollTo()
