/**

*/

const customElements = {
    elements: {
        pricing: { // define all customizable elements within the pricing table view here
            tiers: [
                {
                    name: "Basic", // your tier name to be customized
                    highlighted: {
                        element: customHighlightedBasic // your custom element for this tier's highlight
                    },
                    select: {
                        element: customSelectBasic // your custom element for select button for this tier.
                    },
                    prices: [
                        {
                            id: "price_1jw91203djejd23", // your Stripe price id displayed in this tier.
                            element: customPrice // your custom element for price item in the table.
                        }
                    ]
                }
            ]
        },
        checkout: { // define all customizable elements within the checkout view here
            prices: [
                {
                    id: "price_1jw91203djejd23", // your Stripe price id displayed in this checkout form.
                    description: {
                        element: customDescription, // your custom element for this price description
                    },
                    price: {
                        element: customPriceDisplay, // your custom element for this price display
                    }
                }
            ]
        }
    }
}
Custom element API
The interface to this custom element api is the same for each element level as follows:
{
    type: "div", // Required, the element wrapping element type.
    props: {}, // Optional, the props you'd like to pass to the wrapping element, such as className.
    render: (props) => { // Optional instead of children, allows you to return HTML with dynamic values.
        // prop are based on the current element being customized, 
        // data properties would be for example, the Stripe price
        // object if customzing a price item.
        console.log("Log the props to see what's available to you", props)
        const { unit_amount } = props 
        return `<div>${unit_amount} per month</div>`
    },
    children: "Static Text" // Optional instead of render, if you simply want to customize it with static text.
}
Examples
There are times when you want to customize the pricing information in the pricing table or even add extra elements to it. We will show you how to do it with the following examples.

Pricing: Pricing Items
This section describes how you can customize the Pricing Items like the following example. 
Customized Basic Tier (Left) Price Item Example
To customize a pricing item, you will first create a custom pricing item element like this.
/** Create the custom pricing item */
const CustomBasicPrice = {
  id: "price_HDa0zWHKXsY2sb", // replace with your own Stripe price id
  element: {
    type: "div",
    render: (props) => {
      // props is the price object in this case
      const { currency, unit_amount, priceRenderer } = props;
      const price = priceRenderer({amount: unit_amount ,currency})
      return `<div>
          ${price} <span>/ mo.</span>
          <i>Send up to 100,000 emails/mo before overages apply.</i>
        </div>`;
    }
  }
}
The id specifies the Stripe price item to customize within the tier.
The element is the custom element you will create.
