This document presents the list of available Slots that you can use for adding your custom content (Fill).

If you want to add a new SlotFill component, check the [Checkout - Slot Fill document](../../../../packages/checkout/slot/README.md). To read more about Slot and Fill, check the [Slot and Fill document](./slot-fills.md).

**Note About Naming:** Slots that are prefixed with `Experimental` are experimental and subject to change or remove. Once they graduate from the experimental stage, the naming would change and the `Experimental` prefix would be dropped. Check the [Feature Gating document](../../../internal-developers/blocks/feature-flags-and-experimental-interfaces.md) from more information.

## ExperimentalOrderMeta

This Slot renders below the Checkout summary section and above the "Proceed to Checkout" button in the Cart.

```ts
const { __ } = window.wp.i18n;
const { registerPlugin } = window.wp.plugins;
const { ExperimentalOrderMeta } = window.wc.blocksCheckout;

const render = () => {
	return (
		<ExperimentalOrderMeta>
			<div class="wc-block-components-totals-wrapper">
				{ __( 'Yearly recurring total ...', 'YOUR-TEXTDOMAIN' ) }
			</div>
		</ExperimentalOrderMeta>
	);
};

registerPlugin( 'slot-and-fill-examples', {
	render,
	scope: 'woocommerce-checkout',
} );
```

### Passed parameters

-   `cart`: `wc/store/cart` data but in `camelCase` instead of `snake_case`. [Object breakdown.](https://github.com/woocommerce/woocommerce-gutenberg-products-block/blob/c00da597efe4c16fcf5481c213d8052ec5df3766/assets/js/type-defs/cart.ts#L172-L188)
-   `extensions`: external data registered by third-party developers using `ExtendSchema`. If you used `ExtendSchema` on `wc/store/cart` you would find your data under your namespace here.
-   `context`, equal to the name of the Block in which the fill is rendered: `woocommerce/cart` or `woocommerce/checkout`

## ExperimentalOrderShippingPackages

This slot renders inside the shipping step of Checkout and inside the shipping options in Cart.

```ts
const { __ } = window.wp.i18n;
const { registerPlugin } = window.wp.plugins;
const { ExperimentalOrderShippingPackages } = window.wc.blocksCheckout;

const render = () => {
	return (
		<ExperimentalOrderShippingPackages>
			<div>{ __( 'Express Shipping', 'YOUR-TEXTDOMAIN' ) }</div>
		</ExperimentalOrderShippingPackages>
	);
};

registerPlugin( 'slot-and-fill-examples', {
	render,
	scope: 'woocommerce-checkout',
} );
