I am currently using the parallax theme and wanted to create an element similar to Allbirds.com.
As you can see when you scroll through the website you have the option to quick add based on variant. How can I add this to my site?
As a bonus how to I implement a sliding checkout similar to this:
This is now simple code to share here, you have to hire developer for that.
I can assist you, For that you can edit code in Snippet ->product-grid.liquid or Snippet->product-card.liquid file and add show variants on this file.
then we have any post here to add direct product to cart then you have to implement cart drawer as you want.
