How to Add a Back-to-Top Button in Shopify Broadcast Theme

A back-to-top button is a small floating control that appears once a shopper scrolls down, letting them jump straight back to the header — a native Broadcast setting, useful given how long a feature-rich product or collection page can get.

Steps

1. In your Shopify admin, go to Online Store > Themes and click Customize on Broadcast.
2. Click Theme settings, then look for a Back to top (or similarly named) setting.
3. Turn it on.
4. Click Save.

This is a small detail, but it matters more on Broadcast than on a simpler theme — with tabs, upsells, reviews, and multiple sections stacked on a single product page, "scroll all the way back up" is a real friction point without it.
