I'll create a React component that implements the refund initiation flow you've described. Here's a comprehensive implementation:

This component implements the refund initiation flow you described. Here's a breakdown of its features:

1. Order Number Input: An input box for entering the order number.
2. Reason Dropdown: A dropdown menu for selecting the reason for the refund.
3. Food Status Dropdown: A dropdown to select whether the food was served or not served.
4. Payment Status Dropdown: A dropdown to indicate if the order was paid or not paid.
5. Order Summary: A mock order summary is displayed, showing the items, their prices, and the total.
6. Refund Button: When clicked, it calculates and displays the refund amount (in this mock version, it simply returns the total order amount).
7. Submit Button: Submits the refund request.
8. Success Popup: An alert dialog that appears when the refund request is submitted successfully.

The component uses state to manage the form inputs and control the visibility of the refund amount and success popup. In a real application, you would replace the mock data and functions with actual API calls to fetch the order details and submit the refund request.

To use this component, you would typically place it in your page or layout file. For example:

This creates a full-page layout for the refund flow. You can adjust the styling and layout as needed to fit your application's design.

Remember to handle error cases, validate inputs, and integrate with your backend API in a production environment. Also, consider adding loading states for asynchronous operations like fetching order details or submitting the refund request.

I'll modify the RefundFlow component to include individual refund buttons for each food item in the order summary, show the refunded amount, and update the submit refund request functionality. Here's the updated implementation:

I've updated the RefundFlow component to include the new functionality you requested. Here's a summary of the changes:

1. Each food item in the order summary now has its own refund button.
2. Clicking the refund button toggles the item's refund status and updates the button text to "Refunded".
3. The refunded amount is calculated dynamically based on the items marked for refund.
4. The "Submit Refund Request" button now triggers a popup modal when clicked.

Here's a breakdown of the key changes:

1. Updated the OrderItem interface to include a refunded property.
2. Added a handleItemRefund function to toggle the refund status of individual items.
3. Implemented a calculateRefundAmount function to dynamically calculate the total refund amount.
4. Updated the order summary section to display refund buttons for each item.
5. Modified the "Submit Refund Request" button to show the popup modal with the calculated refund amount.

The component still maintains all the previous functionality, including the order number input, reason dropdown, food status, and payment status selections.

To use this updated component, you can keep the same page structure as before:

This implementation provides a more interactive and detailed refund process, allowing users to select specific items for refund and see the total refunded amount before submitting the request.
