Instruct UI - An AI for Blazor UI Generation
## What's implemented
- Tabbed identity UI with three areas: Users, Roles, and Claims.
- Filterable, pageable MudDataGrid lists with multi-select and toolbar actions.
- Search inputs and quick-filter functions for each grid.
- Create / Edit dialogs built with MudDialog and MudForm (validation via @bind-IsValid).
- Role-permissions matrix: permission rows with MudCheckBox to assign claims to a selected role.
- Per-row action menus (MudMenu) for edit/delete operations.
## Key components
- MudTabs, MudTabPanel
- MudDataGrid<T> with SelectColumn, PropertyColumn, TemplateColumn, MudDataGridPager
- MudTextField (search), MudButton, MudMenu, MudMenuItem
- MudDialog, MudForm, MudSelect (MultiSelection), MudSelectItem, MudCheckBox
- Model classes: UserModel, RoleModel, ClaimModel, RolePermissionModel
- Bindings: @bind-Value, @bind-SelectedItems, @bind-SelectedValues, @ref on MudForm
## How it works
- Grids receive in-memory collections (_users, _roles, _claims) and use QuickFilter callbacks (UserQuickFilter, RoleQuickFilter, ClaimQuickFilter) to implement search/filter behavior.
- Selection is two-way bound via @bind-SelectedItems; toolbar actions operate on the selected sets (_selectedUsers, _selectedRoles, _selectedClaims).
- Dialogs reuse MudForm and @bind-IsValid to validate required fields before Save methods run; Save methods add/update in-memory lists and close dialogs.
- Role permission rows are built from ClaimModel items into RolePermissionModel rows; SaveRolePermissions maps checked rows back to the selected role as "Type:Value" strings.
## Styling
- UI uses MudBlazor components for structure and Material icons (Icons.Material.Filled.*).
- Tailwind utility classes appear for layout and spacing (flex, grid, gap-*, p-*, md:grid-cols-2, etc.) to provide basic responsive arrangement alongside MudPaper.
- MudDataGrid properties (Dense, Hover, Elevation) tune compactness and visual density.
## Reuse steps
1. Add NuGet: MudBlazor package and register MudBlazor services in Program.cs (builder.Services.AddMudServices()).
2. Import namespaces: @using MudBlazor in the component and add MudBlazor CSS and theme in index.html/_Host.cshtml.
3. Add Tailwind or replace utility classes: include Tailwind build or adjust markup classes to match project CSS.
4. Copy models (UserModel, RoleModel, ClaimModel, RolePermissionModel) and the Razor component into a feature area; adjust namespaces.
5. Replace SeedData and in-memory lists with real services (IUserService, IRoleService, IClaimService) and call StateHasChanged when data updates.
## Limitations & next steps
- Current implementation uses in-memory collections; persistence, APIs, and DI service wiring are required for production.
- No authentication/authorization integration is included; protect the page and actions with ASP.NET Core Identity or policy checks as needed.
- Error handling and server-side validation are minimal; add try/catch, transactional updates, and API error feedback.
- Consider paging and server-side filtering for large datasets instead of client-side QuickFilter.
- Accessibility and keyboard interactions for complex grids and dialogs may need review and enhancement.
