Add the Sticky add to cart block

Show a bar with the product and a copy of your Add to cart button after shoppers scroll past the button.

Updated November 4, 2026

The Sticky add to cart block shows a bar at the bottom of the screen once a shopper scrolls past your Add to cart button. The bar shows the product image, the name, the variant and a copy of your button. Its button clicks your real one, so it adds what the buy box has selected.

Before you start

You need Section Store Plus or its free trial.

Add the block

  1. In Shopify admin, open Apps → Section Store → Conversion Blocks.
  2. On the Sticky add to cart card, click Edit In Theme.
  3. Pick your theme. Your live theme has a green dot.
  4. The theme editor opens on your product template with the block added.
  5. Click Save.

The block's place in the list doesn't matter, because the bar always sits at the bottom of the screen.

How the bar behaves

  • It shows after the theme's button scrolls off the top of the screen. It hides when the button comes back.
  • The button copies your theme's button, including Atc button styling.
  • The variant line and Change link show only on products with more than one variant.
  • Change scrolls back to the buy box. The shopper picks the variant there.
  • Selected add-ons from the Addons block go in the cart too.
  • A page shows one bar, even with two blocks.
  • With no Add to cart button on the page, no bar shows.
