Responsive Chatpage Design

Responsive chat UI built with MudBlazor. MudBlazor Chat Page uses MudChat bubbles and MudTextField binding, a contact sidebar, and grouped messages for conversation display.

## What's implemented - Sidebar with searchable contact list and selectable contact rows. - Responsive chat area with grouped messages and left/right message alignment. - Message rendering using MudChat and MudChatBubble components with avatars and timestamps. - Message input area with MudTextField bound to _currentMessage and a Send button that appends messages. - Mobile header variant using MudHidden to toggle sidebar/header visibility. ## Key components - MudContainer, MudAppBar, MudGrid, MudItem, MudPaper - MudHidden (Breakpoint.MdAndDown / MdAndUp) - MudTextField (T="string") with @bind-Value - MudChat, MudChatBubble, MudAvatar - MudButton, MudIconButton, MudText ## How it works - Contacts are rendered from a List<string> _contacts; selecting a contact sets _selectedContact via SelectContact(Contact). - Messages are stored in an in-memory List<ChatMessageModel> _messages. SendMessage() appends a new ChatMessageModel and clears _currentMessage. - GetGroupedMessages() groups consecutive messages by sender and ownership (IsOwn) to render message groups with MudChat positioned Start/End. - UI state uses @bind-Value for _searchText and _currentMessage and uses foreach loops to render lists; click handlers use lambda event callbacks. ## Styling - Uses MudBlazor components and utility classes (d-flex, pa-*, px-*, border-*, ml-*, mr-*) for layout and spacing. - Responsive behavior relies on MudHidden and MudGrid column sizes (xs/sm/md/lg/xl). - No Tailwind or Bootstrap detected; styling is provided by MudBlazor theme and component classes. ## Reuse steps 1. Add the MudBlazor NuGet package to the project (MudBlazor). 2. Register MudBlazor services in Program.cs (builder.Services.AddMudServices()). 3. Include MudBlazor CSS and icons in the layout/_Host (MudBlazor.min.css, Material icons). 4. Import MudBlazor namespace in _Imports.razor or the component file (@using MudBlazor). 5. Copy ChatPage.razor and ChatMessageModel.cs, adjust model properties and bindings to match the app domain. 6. Replace in-memory lists with a messaging back end (SignalR, API) and implement message loading for SelectContact. ## Limitations & next steps - No real-time transport is wired; integrate SignalR or a backend push mechanism for live updates. - Contacts and messages are in-memory sample data; persistence and pagination are required for production. - Search input (_searchText) is not applied to filter contacts; implement filtering logic. - Authentication and authorization are not covered; secure endpoints and user identity are needed. - Accessibility and internationalization are not addressed; add aria attributes and localization as required.
