This setting is rarely needed but it will tell UpCart to completely re-render all of your cart's Custom HTML elements every time the cart is updated.

We recommend using this setting if you realize some of your custom elements have numbers that aren't updating.

For example, let's say you may have a subtotal line that's separate from the Checkout button. Let's pretend that the subtotal number isn't updating correctly, enabling this setting may fix that.

When enabled, this will re-render all elements you've created in the Custom HTML section of UpCart's settings tab. This ensures that the element is up to date but does make things slightly slower since a re-render was done.

When disabled, the elements you've created in the Custom HTML section of UpCart's settings tab will re-render only as needed.
