**How was the live product customizer (Raglan Shirt demo) built with Infinite Options?**

This example is a great illustration of what is possible when you combine Infinite Options with custom development using the Infinite Options Events API.

{% hint style="info" %}
This is not a built-in Infinite Options feature. It requires custom coding to connect option selections to the layered artwork and real-time preview behavior. If you'd like something similar on your store, we recommend working with a Shopify Expert. The team at [Hey Carson](https://app.shopexperts.com/client/new-project?ref=shoppad) has experience building setups like this and can help scope the work based on your needs.

Infinite Options collects the shopper's selections. On top of that, the **Infinite Options Events API** and custom scripts were used to:

* toggle layered PNG images in real time based on choices
* apply visual updates as selections change
* update SVG text for the monogram field so shoppers can preview personalization instantly
