Sticky Add to Cart Button That Triggers Main Add to Cart Button

Shopify Discussion

Topic summary

A user with the Prestige theme needs to create a sticky add-to-cart button that programmatically triggers the main add-to-cart button on their product page.

The Challenge:

  • Product page includes customization apps (photo upload, custom text) and quantity breaks (2-pack, 3-pack options)
  • These customizations only transfer to cart when using the main add-to-cart button
  • Standard sticky add-to-cart apps won’t work because they bypass the main button, losing customer selections

Requested Solution:
Manual code for a sticky button positioned in the bottom corner that acts as a trigger/shortcut to click the main add-to-cart button, preserving all selected customizations.

Hi everyone,

I currently have the Prestige theme, and my product page includes customization apps (such as photo upload and custom text) and quantity breaks (such as 2 packs and 3 packs) that only bring the selected options into the cart if the customer hits the main add to cart button — as a result, sticky add to cart apps are not an option since these will not bring the selected customizations into the cart.

I was wondering how to manually code a sticky add to cart button in the bottom corner of my page that triggers the main add to cart button. Essentially like a coding shortcut where pressing the sticky add to cart button immediately triggers the main add to cart button — thus bringing all the customer’s selected customizations into the cart.

Any help would be much appreciated!

Hi @madebyme1 ,

Do you mean an “Add to Cart” button like in the demo image below?

Besides that, can you provide me with the link to your website?
