How to change Featured Product Layout?

Topic summary

Main issue: In a Featured Product section, thumbnail images stack below the main image. The requester wants a horizontal, clickable thumbnail gallery with navigation arrows, and also reports that “Hide other variants’ media after selecting a variant” does not work (variant images don’t change).

Proposed fixes: A helper first suggested adding Custom CSS via Theme Settings to resize thumbnails; then provided a page-specific CSS solution by inserting a style block in theme.liquid (scoped to a specific page ID) to set small thumbnail sizes and a full-width main image.

Outcome/feedback: The CSS changes only modified layout/size and did not make thumbnails clickable. On the target landing page, thumbnails remained unclickable and too small compared to the product page gallery the requester referenced. The variant-media hiding issue was not addressed by the provided solutions.

Status: Unresolved/ongoing. The requester still needs a horizontally scrolling, clickable thumbnail gallery with arrows like on the product page, and a fix for variant-specific media behavior. Screenshots were shared to illustrate the current and proposed layouts.
