Collapsible Checkout Sections with Checkout Extensibility

Topic summary

A developer is seeking to implement collapsible checkout sections that expand progressively as customers complete each step, similar to Adidas’s checkout flow.

Key Requirements:

  • Sections collapsed by default
  • Each section unlocks only after the previous one is completed
  • Sequential, step-by-step progression through checkout

Current Status:

  • The client wants this functionality but it’s not currently available on their Shopify Plus store
  • Question remains open about whether Checkout Extensibility supports this pattern or if similar solutions exist

The post includes reference images showing the Adidas checkout implementation as the desired example.

I have a client who would like their checkout sections to be collapsed by default, and after the customer populates the details of each step, the following step becomes available. Similar to how Adidas currently show it on their Checkout.

Is this possible with Checkout Extensibility or similar? They aren’t currently on Plus.

To my knowledge this is not possible with Checkout Extensibility. For the most part you can only add new sections or fields and just adjust the style, but making these existing fields collapsable is not possible as of right now.
