Hide Properties Starting With Single Underscore "_"

Control whether internal or app-generated product attributes are shown in the cart drawer.

Overview

This setting hides any line item properties that begin with a single underscore (_). These are often added by third-party apps or custom scripts to store internal data, such as personalization info or product metadata.

This setting only affects visibility in the Upcart cart drawer. Your Shopify theme’s cart page may still display these properties.

Where to Find It

Upcart > Editor > Settings > Advanced Settings
Look for “Hide properties starting with single underscore.”

How It Works

Enabled

Any line item properties starting with _ will be hidden from the cart drawer. This keeps the layout clean and avoids showing technical or irrelevant data to customers.

Disabled

These properties will remain visible. This can be helpful if you want customers to review their personalization choices or see other custom product details.
