This block reads live subscription data, so it only runs inside a real customer portal. The animation shows what subscribers see.

What it does

Every other variant of a subscriber’s product, each with a badge and a one-tap Swap or Add.

Why it exists

For merchants selling one product in lots of flavors, scents or sizes. Subscribers see what else exists and can swap or add without leaving the portal.

The code

Paste it as-is, or download full-lineup.html

How to install

  1. Copy the code above, or download the .html file.
Your portal
  1. Go to Storefront → Customer Portal → Branding → Layout and click Add custom extension.
  2. Pick HTML with embedded CSS and JavaScript and paste the whole file into the code editor.
  3. Swap anything the file asks you to, like [BRAND], product names or Quick Action IDs. The AI prompt below can walk you through it.
  4. Save, click + to add it to the layout, then Publish. Check it on a test subscription’s magic link with ?forcePreview=true, since some scripts don’t run in Preview.
Before you paste

Built for one product sold as standalone variants, not variety packs. Edit the VARIANTS array. For one-tap Swap and Add, create Quick Action stacks under Grow → Quick Actions and paste their IDs. Check the data-skio-name selectors against your portal first.

Customize it with AI

Paste this prompt into Claude Code or Codex. It asks for the code and your brand and product details, then writes a version for your store.

Blocks are shared as-is by the people who built them. Read the code before you add it to your portal, and test it with a test subscriber first.
