Keep Add to Cart one tap away, no matter how far they've scrolled
Once a shopper scrolls past the main Add to Cart button, it's gone — past the description, the specs, the reviews. This module shows a sticky bottom bar with the product thumbnail, name, price, and an Add to Cart button, on mobile by default and desktop if you want it too.

A second entry point to the same real button — not a second button
The sticky bar never invents its own add-to-cart logic; it triggers the exact form your theme already renders.
Appears exactly when needed
The bar slides in once the real Add to Cart button scrolls out of view — not on page load, and not before it's actually useful.
Thumbnail, name, and price
Shoppers always see what they're about to buy right in the bar itself, without scrolling back up to check.
Submits the real add-to-cart form
The bar's button doesn't post its own request — it triggers the exact same form your theme already rendered on the page.
Configurable & bundle options still validate
Because it's the real form, required option selections are still enforced exactly as if the shopper had clicked the original button.
Mobile by default, desktop optional
Ships enabled for mobile, where the effect matters most, with a config toggle to turn it on for desktop too.
No second code path to maintain
One real form, one real set of validation rules — the sticky bar is just another visible trigger for it.
Why this exists: a naive sticky add-to-cart implementation builds its own mini button that posts straight to the cart controller with just a product ID — which works for simple products but silently breaks for configurable and bundle products, because it skips the option-selection validation Magento's real form performs before submitting. This module instead locates the theme's actual rendered add-to-cart form on the page and submits that same form element from the sticky bar's button. Whatever validation, required-option checks, and event dispatching your theme already runs still runs exactly the same way — the sticky bar is a second visual entry point to the one real form, never a second implementation of it.
