Place the button with Shopify’s theme editor, enable it for the products you want, and customise its label and colour.
Open Settings → Open theme editor. The link drops you straight into Shopify’s theme editor with the Try-On Button block ready to place. Drag it where you want it, click Save, and it’s live.
In Settings, choose All products, specific products, or whole collections. Start with your bestsellers: engagement compounds where shoppers are already interested.
The try-on follows the variant the shopper has selected and uses that variant’s product image and details when they are available.
