Can the Preorder or Notify me button show on collection pages and the homepage? (Essent Preorder Back in Stock app)

Yes. Both buttons show on product pages by default, and you can add them to collection grids, the homepage, search results, featured product sections and quick buy modals.

Preorder button

Go to Preorder → Settings → General settings → Manage and, under Show preorder button in, turn on Product lists in collection, homepage and search pages, Featured products and/or Quick buy modals (Lite plan or higher). Save and check in an incognito window.

Notify me button

1. Go to Back in stock → Settings → Placements → Show Back in Stock button on and turn on Featured products, Product lists and/or Quick buy modals (Lite plan or higher).
2. Placements beyond product pages also have to be fitted to your theme by our team. Chat with support and ask us to enable the Notify me button outside product pages. It's free.

Limits

• The app replaces your theme's own buy button, so a product card with no Add to cart or Sold out button (only a "View" link) can't show one.
• The preorder badge is a separate setting and shows on product images and product lists.
