# Force Re-Render of Custom HTML Fields

> Refresh all Custom HTML elements whenever the cart updates.

# Overview

This setting forces Upcart to fully re-render any HTML you've added through the Custom HTML editor. It's useful when dynamic content (like custom subtotals or counters) doesn't update correctly on its own.

## Where to Find It

Upcart > Editor > Settings > Advanced Settings\
Look for **"Force re-render of custom HTML fields."**

## How It Works

### Enabled

Upcart will re-render all Custom HTML elements every time the cart updates. This ensures that dynamic content stays in sync, but may slightly affect performance.

### Disabled

Custom HTML elements will only re-render when absolutely necessary. This provides better performance but may cause some elements to lag behind cart changes.
