Variant picker

A product drawn in code that recolors and resizes as you pick.

Pick a color and a size and the product, an SVG drawn in code, changes at once. Colors and sizes come from props, each option is a real button, and a sentence names the current variant for screen readers. Nothing is sold: a pick only tells your page.

Try it

<variant-picker>

Build one with your agent

Paste this into your agent. It asks you before it signs in, pays or goes further than checking and publishing.

Build me a Taggor component like "Variant picker" (variant-picker): A product drawn in code that recolors and resizes as you pick. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
