Instruct UI - An AI for Blazor UI Generation
## What's implemented
- Menu item grid with image, name, description, price and an Add button.
- Instant search/filter input bound with @bind-value and oninput behavior.
- In-memory shopping cart with add, remove, increment/decrement quantity controls.
- Order summary card with subtotal, tax calculation, total, and action buttons (Place Order, Clear Cart, Payment).
- Simple payment modal implemented by toggling a boolean and applying Bootstrap modal classes.
## Key components
- HTML input with @bind-value and @bind-value:event="oninput" for search filter.
- foreach rendering of MenuItemModel into Bootstrap card elements.
- Buttons with @onclick and @onclick:stopPropagation for card vs button clicks.
- Modal markup using Bootstrap classes and a boolean (isPaymentModalOpen) to show/hide.
- Properties and methods: FilteredMenuItems (LINQ), AddToCart, UpdateQuantity, RemoveItem, ClearCart, PlaceOrder, SubTotal/Tax/Total computed properties.
- Models: MenuItemModel, CartItemModel with calculated Total.
## How it works
- The search box updates searchTerm on every keystroke; FilteredMenuItems uses LINQ to filter Name/Description.
- Clicking a card or the Add button invokes AddToCart; existing cart items increase quantity.
- Quantity buttons call UpdateQuantity(change) and remove items when quantity <= 0.
- SubTotal, Tax, and Total are computed from CartItems and rendered in the order summary.
- Payment modal is shown by setting isPaymentModalOpen and toggles CSS classes (show d-block) rather than using Bootstrap JS.
## Styling
- Uses Bootstrap grid and utility classes (container-fluid, row, col-*, card, btn, input-group, form-control) and Font Awesome icons.
- Cards use responsive columns (col-md-6, col-xl-4) for desktop-to-mobile layout.
- Order summary uses sticky-top for a persistent right column on large viewports.
- Modal uses a simple backdrop via inline style and class toggling; no Bootstrap JS dependency is required but recommended for full accessibility.
## Reuse steps
1. Add the Razor file and the MenuModels.cs to a Blazor Server or WebAssembly project; ensure _Host.cshtml or index.html includes Bootstrap and Font Awesome.
2. Import namespaces where needed and add the component to a page or navigation (e.g., <SalesConsole />).
3. Replace the in-memory MenuItems with a service or API: add an interface, register it in Program.cs, and inject it into the component.
4. Persist cart state as required (local storage, scoped service, or server-side session) and implement a payment API for PlaceOrder/OpenPaymentModal.
5. Optional: replace modal CSS toggle with Bootstrap JS or a Blazor modal component for improved accessibility and focus management.
## Limitations & next steps
- Payment is a placeholder; no payment gateway integration or server-side order processing is provided.
- No validation UI for checkout details and no user authentication or authorization is included.
- Modal accessibility and keyboard focus are not fully handled by the CSS toggle approach.
- Concurrency, persistence, and error handling require backend services and state management integration.
- Next steps: wire a cart service, implement checkout form with validation (EditForm/DataAnnotationsValidator), and connect to a payment API.
