Getting started with Luv Sticky Add To Cart

1. Install and open

Install Luv Sticky Add To Cart and open it from Apps in your Shopify admin. You land on the Design page with a live product-page preview.

2. Design both views

Use the Desktop and Mobile tabs — each has its own bar height, button wording, button placement, and its own choice of what shows in the bar (product photo, title, price with sale strikethrough). Colors, button roundness, and font are shared. The mini product page in the preview scrolls like the real thing: the bar appears once the buy box scrolls out of view.

3. Pick your dropdowns

Three checkboxes: a variant dropdown (hidden automatically on single-variant products), a subscription dropdown (appears only on products with selling plans — one-time vs. subscribe), and a quantity dropdown. Adds go through your theme's own cart, so your cart drawer and events keep working.

4. Turn it on and verify

Online Store 2.0: use the Install page's deep link to your theme editor's App embeds, switch on Luv Sticky Add To Cart, and Save. Any other theme: paste the one-line script before </body> in theme.liquid — the bar only renders on product pages. The status pill turns green Live once detected, and Preview on store shows the bar forced visible so you can check the design instantly.
