How to Enable Quick Add in Shopify Broadcast Theme

Quick Add lets a shopper add a product to their cart without leaving the collection page — products with no variants add instantly with one click, while products with variants open a small drawer to pick options first.

Steps

1. In your Shopify admin, go to Online Store > Themes and click Customize on Broadcast.
2. Click Theme settings, then Product Grid.
3. Find the Quick Add setting and turn it on.
4. Click Save.

This is a single global toggle rather than something set per collection — once it's on, it applies to product grids across the store.
