Mobile thumbnails

By default, the mobile gallery shows arrows + dots only — thumbnail strips are hidden to maximise vertical space. Toggle them back on if your products benefit from a thumbnail row.

Setting

Customize → Product → Show thumbnails on mobile (checkbox, default off).

Behavior

When enabled:

• Slider gallery → thumbnails render as a horizontal scrollable strip below the main image
• Grid layouts → a separate horizontal thumbnail strip appears below the main carousel
• Tap a thumbnail → switches to that image (and scrolls the strip if needed so the active thumb stays visible)
• Native horizontal scroll on the strip — drag with finger

When to enable

• 8+ images per product (dots become unreadable on phones)
• Customer needs to compare multiple angles at-a-glance

When to keep off

• 4 or fewer images — dots are fine
• Tall vertical lookbook shots — strip eats vertical space

Tips

• Combined with arrow nav (also auto-scrolls active thumbnail into view), the experience matches modern mobile commerce flagships.
