1. Solution

• Current status (ABP Studio CLI 9.2.x): There is no supported way to drop a custom ZIP into ~/.abp/templates or to point ABP Studio CLI to a custom template folder. That directory is a managed download cache and is overwritten by clear-download-cache and by template updates. Overriding the built-in template download behavior is not supported.

• Recommended, supportable approaches to standardize your organization’s starting point:

  1. Create an Organization Base Solution once, and reuse it

     • Create a new solution with the official template that matches your target ABP/Commercial version (e.g., app-pro for Commercial).
     • Apply all organization-wide changes (base classes, conventions, utility code, settings, CI files, common modules/packages, theme defaults, etc.).
     • Store it in your internal Git repo as a seed project.
     • Workflow for new projects:
       • Clone the base solution as a new repo.
       • Rename namespaces, solution and project names with your own script or tooling.
       • Update Solution Configuration (if needed) and run migrations.
     • Pros: 100% control; survives upgrades; no reliance on CLI “custom templates.”
     • Notes: Keep the base solution synchronized with ABP version updates you plan to use in new projects.

  2. Package your reusable code into modules and NuGet/npm packages

     • Move base classes, common abstractions, shared UI pieces, and utilities into one or more internal ABP modules (backend NuGet packages and, if Angular, npm packages).
     • Start new projects from the official template and immediately add your internal modules via abp add-package / dotnet add package (and Angular equivalents).
     • Pros: Keeps startup templates standard and upgrades simpler; consistent reuse across solutions.

  3. ABP Suite/Studio automation (optional)

     • Use ABP Suite for repetitive CRUD scaffolding and conventions, and keep your customizations in modules and post-create scripts.
     • This does not replace a “custom template,” but reduces manual steps right after creation.

• ABP CLI vs ABP Studio CLI regarding templates:

  • The legacy ABP CLI (Volo.Abp.Cli) historically supported template source configuration in some older docs, but the current ABP Studio CLI manages and downloads official templates by version. Using the old CLI alongside Studio is not recommended for creating Commercial solutions in 9.x. The Studio CLI is the supported path for project creation and will still not load user ZIPs from ~/.abp/templates.
  • Practical guidance: Do not install or rely on the legacy CLI to inject custom templates. Use the base-solution or reusable-module approaches above.

• Answer to your specific attempts:

  • Placing app-pro-9.2.0.zip under ~/.abp/templates: Not supported; cache is controlled by the CLI and will be ignored/overwritten.
  • clear-download-cache: Correct observation; it confirms the folder is a managed cache, not an extension point.

• Minimal example of an internal module approach

[DependsOn(
      typeof(AbpIdentityApplicationModule) // and other dependencies your base module needs
  )]
  public class MyCompanyBaseApplicationModule : AbpModule
  {
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          // Configure organization-wide conventions, object mappers, settings, etc.
      }
  }

Then in a newly created project:

• Add a package reference to MyCompany.Base.Application (NuGet).
• Add DependsOn(typeof(MyCompanyBaseApplicationModule)) to the Application module.
• For UI (Angular), publish @myco/abp-ui packages and add them right after creation.

1. Solution The exception means an endpoint discovered by ApiExplorer (OpenAPI/Swagger) is coming from a conventionally-routed action. In your case, it’s the generated client proxy for Volo.Docs Admin (DocumentPdfAdminClientProxy.GeneratePdfAsync). This happens when MVC’s conventional controller discovery and the client proxy (which ApiExplorer thinks is an API surface) are both in the pipeline without proper attribute routing metadata.

Apply one of the following fixes (prefer the first):

• Fix A: Exclude client proxy types from ApiExplorer Add an MVC option to ignore ApiExplorer for the Docs Admin HttpApi Client assembly types.

using Microsoft.AspNetCore.Mvc;
  using Microsoft.Extensions.DependencyInjection;
  using Volo.Docs.Admin.HttpApi.Client; // for assembly reference

  public override void ConfigureServices(ServiceConfigurationContext context)
  {
      // ... your existing registrations

      Configure<MvcOptions>(options =>
      {
          options.Conventions.Add(new ApiExplorerVisibilityConvention(type =>
              type.Assembly == typeof(DocsAdminHttpApiClientModule).Assembly,
              isVisible: false));
      });
  }

  // helper convention
  public sealed class ApiExplorerVisibilityConvention : Microsoft.AspNetCore.Mvc.ApplicationModels.IApplicationModelConvention
  {
      private readonly Func<Type, bool> _typePredicate;
      private readonly bool _isVisible;

      public ApiExplorerVisibilityConvention(Func<Type, bool> typePredicate, bool isVisible)
      {
          _typePredicate = typePredicate;
          _isVisible = isVisible;
      }

      public void Apply(Microsoft.AspNetCore.Mvc.ApplicationModels.ApplicationModel application)
      {
          foreach (var controller in application.Controllers)
          {
              if (_typePredicate(controller.ControllerType.AsType()))
              {
                  controller.ApiExplorer.IsVisible = _isVisible;
              }
          }
      }
  }

Explanation: The Docs HttpApi Client assembly contains typed client proxies (used by your Web app to call the Docs service). They are not real MVC API controllers and shouldn’t participate in ApiExplorer/endpoint discovery. This convention hides them from ApiExplorer to prevent the “ApiExplorer enabled + conventional routing” conflict.

• Fix B: Disable ApiExplorer at controller/action level (if you have access) If a specific generated/proxy controller is being picked up, you can add:

[ApiExplorerSettings(IgnoresApi = true)]

on the controller or action. However, for generated client proxies, Fix A is more robust.

• Fix C: Ensure all discovered controllers use attribute routing (not recommended here) Converting affected controllers to attribute routing resolves the mismatch, but since the offending type is a client proxy (not meant to expose HTTP endpoints), hiding it from ApiExplorer is the correct approach.

• About MapMetrics and UseConfiguredEndpoints The crash occurs when endpoints are finalized (app.UseConfiguredEndpoints), where MVC builds its action descriptors. The above fix prevents the proxy from being treated as an MVC action, so MapMetrics and endpoint configuration can proceed normally.

1. Solution In the ABP Azure Blob Storing provider (Volo.Abp.BlobStoring.Azure), the commonly documented configuration options are ConnectionString, ContainerName, and CreateContainerIfNotExists. The official documentation does not list an AccountName option, and there is no verified ABP doc indicating a specific version that introduces an “AccountName” property for the Azure provider configuration.

To use Azure AD/Managed Identity with ABP’s Azure Blob provider based on verified guidance:

• Continue using the provider by omitting ConnectionString and rely on standard Azure SDK patterns only if/when ABP officially supports such configuration in docs or package notes.
• As of the referenced docs, the supported documented properties are:
  • ConnectionString
  • ContainerName
  • CreateContainerIfNotExists

If you need AccountName-style configuration, check your installed Volo.Abp.BlobStoring.Azure package’s API surface (e.g., via IntelliSense or source) and release notes. If it’s not present, you must use ConnectionString-based auth per current official docs, or implement a custom blob provider that uses DefaultAzureCredential.

1. Solution To move ABP’s Azure Blob storage integration from account keys to Managed Identity (MSI) with Azure AD RBAC, configure the ABP Azure Blob provider to authenticate via DefaultAzureCredential and grant your App Service identity the proper RBAC role on the storage account.

Steps:

• Install and enable the Azure Blob provider in your ABP module

using Volo.Abp.Modularity;
  using Volo.Abp.BlobStoring;
  using Volo.Abp.BlobStoring.Azure;

  [DependsOn(typeof(AbpBlobStoringAzureModule))]
  public class MyProjectDomainModule : AbpModule
  {
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          var configuration = context.Services.GetConfiguration();

          Configure<AbpBlobStoringOptions>(options =>
          {
              options.Containers.ConfigureDefault(container =>
              {
                  container.UseAzure(azure =>
                  {
                      // Use AAD/MSI instead of connection string:
                      azure.AccountName = configuration["Blob:AccountName"];      // e.g. mystorageacct
                      azure.ContainerName = configuration["Blob:ContainerName"];  // e.g. app-blobs
                      azure.CreateContainerIfNotExists = true;

                      // When no ConnectionString is provided, the provider will use Azure SDK credentials.
                      // With DefaultAzureCredential in App Service, MSI will be used automatically.
                      // Optionally, you can set an explicit endpoint (useful for national clouds):
                      // azure.BlobServiceEndpoint = $"https://{azure.AccountName}.blob.core.windows.net";
                  });
              });
          });
      }
  }

App settings (no keys):

"Blob": {
    "AccountName": "mystorageacct",
    "ContainerName": "app-blobs"
  }

• Assign RBAC to the Managed Identity of your App Service

  • In Azure Portal, enable a System-assigned Managed Identity on your App Service.
  • On the Storage Account -> Access Control (IAM) -> Add role assignment:
    • Role: Storage Blob Data Contributor (minimum for read/write) or Storage Blob Data Owner if you need container management.
    • Assign to: Your App Service’s managed identity.
  • Wait a few minutes for propagation.

• Ensure the Azure SDK uses Managed Identity at runtime

  • The ABP Azure provider (Volo.Abp.BlobStoring.Azure) builds the Azure Blob client with Azure SDK. If you omit ConnectionString and provide AccountName (and optionally BlobServiceEndpoint), the Azure SDK will rely on DefaultAzureCredential. In App Service, DefaultAzureCredential picks up MSI automatically. No code change is needed in your application layer that uses IBlobContainer.

• Verify locally with developer credentials (optional)

  • Locally, DefaultAzureCredential will try environment variables, Visual Studio/VS Code/Azure CLI login. For local dev using AAD, sign in with Azure CLI:
    • az login
    • Ensure your dev principal has access to the storage account (e.g., Storage Blob Data Contributor) to test without keys.

• Using named containers (optional)

[BlobContainerName("profile-pictures")]
  public class ProfilePictureContainer {}

  Configure<AbpBlobStoringOptions>(options =>
  {
      options.Containers.Configure<ProfilePictureContainer>(container =>
      {
          container.UseAzure(azure =>
          {
              azure.AccountName = configuration["Blob:AccountName"];
              azure.ContainerName = "profile-pictures";
              azure.CreateContainerIfNotExists = true;
          });
      });
  });

Notes:

• Do not set azure.ConnectionString when using MSI. Providing a connection string forces key-based auth.
• If you need to target sovereign clouds, set azure.BlobServiceEndpoint accordingly.
• Ensure your module includes [DependsOn(typeof(AbpBlobStoringAzureModule))] and Volo.Abp.BlobStoring.Azure package.

1. Solution

• Root cause

  • In ABP, modification audit properties (LastModificationTime/LastModifierId) are set by ApplyAbpConcepts during SaveChanges only when EF Core reports the entity as Modified. Historically, changing only a navigation/foreign key could be missed by EF change detection, so audit fields were not updated.
  • From ABP 8.3 onward, the framework explicitly updates ModificationAuditProperties when a navigation property changes. On earlier versions (like 9.2.3 is newer than 8.3, so it already includes this behavior), you should get updates if the FK or navigation change is tracked as a modification within the same DbContext/Unit of Work.

• What to verify in your app

  1. Ensure updates happen inside a Unit of Work and the same DbContext instance tracks the entity and the FK change before SaveChanges.
     • Use repository.GetAsync(id), mutate tracked entity’s AuthorId (or navigation), then await repository.UpdateAsync(entity, autoSave: true) or rely on UoW completion.
  2. Change the FK scalar property, not only the navigation proxy:

var book = await _bookRepository.GetAsync(id);
     book.AuthorId = input.AuthorId; // set the FK scalar
     // or set book.Author = await _authorRepository.GetAsync(input.AuthorId);
     await _bookRepository.UpdateAsync(book, autoSave: true);

3. Do not use ExecuteUpdate/ExecuteDelete bulk operations for this scenario; they bypass EF tracking, so ABP auditing (including modification audit fields) will not run.
4. Make sure CurrentUser is available if you expect LastModifierId. If the operation is AllowAnonymous or executed by background processes, LastModifierId may be null unless you set a principal:

var claims = new List<Claim> { new Claim(AbpClaimTypes.UserId, userId.ToString()) };
     using (_currentPrincipalAccessor.Change(claims))
     {
         await _bookRepository.UpdateAsync(book, autoSave: true);
     }

5. If you’re attaching a detached entity (e.g., mapping DTO to new entity instance and calling UpdateAsync), ensure EF knows which properties changed. Prefer fetch-and-mutate; otherwise you may need to mark the FK property as modified on the DbContext entry.

• ABP 8.3+ behavior (applies to 9.2.3)

  • ABP updates ModificationAuditProperties when navigation properties change. If you still see no update:
    • Confirm that AuthorId change results in EF change tracker marking the entity as Modified.
    • Confirm the change is not done via raw SQL or bulk update APIs.
    • Confirm the update path is not suppressing ApplyAbpConcepts (e.g., custom DbContext SaveChanges override that skips base behavior).

• Minimal working example

public class BookAppService : ApplicationService
  {
      private readonly IRepository<Book, long> _bookRepository;

      public BookAppService(IRepository<Book, long> bookRepository)
      {
          _bookRepository = bookRepository;
      }

      public async Task UpdateAuthorAsync(long id, long? newAuthorId)
      {
          var book = await _bookRepository.GetAsync(id); // tracked
          book.AuthorId = newAuthorId;
          await _bookRepository.UpdateAsync(book, autoSave: true); // triggers ApplyAbpConcepts
          // After save, LastModificationTime and LastModifierId should be updated (if CurrentUser.Id exists)
      }
  }

• If you must use detached updates

var book = await _bookRepository.GetAsync(id);
  _ = ObjectMapper.Map(input, book); // ensure AuthorId ends up different
  await _bookRepository.UpdateAsync(book, autoSave: true);

• Summary
  • With ABP 9.2.3, changing a FK/navigation should update LastModificationTime/LastModifierId provided:
    • The change is tracked by EF in a normal UoW (not bulk ops/raw SQL).
    • You change the entity instance fetched from repository (tracked).
    • CurrentUser is set if you expect LastModifierId.
  • If your code path still does not update the audit fields, refactor to fetch-and-mutate within the repository/UoW as shown above.

1. Solution

• Root cause

  • After you granted many permissions, the authenticated principal carries a large number of claims. With cookie-based auth on IIS, these claims are serialized into the auth cookie. IIS (http.sys) enforces request header size limits; when the cookie grows beyond those limits you get “HTTP Error 400. The size of the request headers is too long”.

• Fix (recommended)

  1. Reduce auth cookie size

     • Assign permissions to roles and add the user to roles instead of assigning hundreds of permissions directly to the user.
     • Remove/limit any custom claims you add via contributors or a custom ClaimsPrincipalFactory.
     • Avoid putting permission names as individual claims; rely on ABP’s permission check on the server side instead of duplicating all permissions in the cookie.

  2. Use tokens that don’t bloat headers

     • If you use the Auth Server (OpenIddict), prefer bearer access tokens on API calls (Authorization: Bearer …) and keep the cookie principal minimal for the interactive login. Do not mirror every permission in claims.

  3. IIS-specific mitigations (if you still need more room)

     • Increase http.sys header limits (this affects IIS because it sits on http.sys). In registry:
       • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters
         • MaxFieldLength (DWORD, in bytes)
         • MaxRequestBytes (DWORD, in bytes)
       • Reboot the server after changing.
     • You can also raise requestFiltering limits, but that affects URL/query length, not header size. Since the error started after adding permissions, the cookie/header size is the actual culprit, not query string length.

  4. Verify no unnecessary cookies are sent

     • Remove extra cookies and ensure non-browser clients don’t send cookies to API endpoints to avoid additional headers (antiforgery, etc.).

• Minimal ABP-side checklist

  • Review any custom claim contributors:

public class MyClaimsContributor : IAbpClaimsPrincipalContributor
    {
        public Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
        {
            var identity = context.ClaimsPrincipal.Identities.First();
            // Remove or avoid adding large/duplicate claims here
            return Task.CompletedTask;
        }
    }

• Keep user-to-role assignments and let ABP evaluate permissions by definition, not by dumping all permission names into claims.

1. Solution

• Why this happens

  • In ABP, the current user’s permissions are sent to the client as claims. With cookie authentication (React UI + separated AuthServer/tiered), these claims are included in the auth cookie. If you grant a very large number of permissions to a user/role, the cookie grows and can exceed server/proxy/browser header size limits, resulting in “HTTP Error 400. The size of the request header is too long”.

• Fixes (pick one or combine)

  1. Reduce the amount of data stored in the cookie

     • Prefer role-based permissions instead of assigning hundreds/thousands of permissions directly to the user.
     • Remove unnecessary claims you may be adding (custom claims, tenant-specific extras, etc.).

  2. Switch to reference tokens (prevent large cookies to the frontend)

     • If you are using the AuthServer (OpenIddict/IdentityServer), configure access tokens to be reference tokens or keep the principal small and fetch permissions from the API when needed (AuthorizationService / AbpPermissionDefinitionManager) instead of carrying all permission names as claims in the cookie.

  3. Increase header limits on your front-end/reverse proxy if absolutely necessary

     • IIS: increase max request header size limits. Example in web.config for AspNetCoreModuleV2:
       • Add or increase limits in the hosting/reverse proxy layer (IIS/ARR, nginx, Azure App Gateway). Note: This is only a mitigator; it’s better to reduce cookie size.
     • Browsers still have cookie-size limits (~4 KB per cookie and ~8–16 KB per header chunk), so this may not fully solve it.

  4. Ensure antiforgery/cookie settings don’t add extra cookies unnecessarily

     • Don’t send cookies from non-browser clients (Postman/mobile). Carrying cookies can trigger antiforgery and add more headers, compounding the size. See ABP guidance: if you remove cookies for API calls, antiforgery isn’t required and avoids extra headers.

• Practical steps to reduce cookie size in ABP

  • Keep permissions assigned to roles; assign users to roles. Avoid assigning long lists of permissions to a single user.
  • Avoid adding each permission as a separate claim at sign-in time. Rely on ABP’s permission checking on the server instead of pushing the full permission list to the client if you customized the claims principal factory.
  • If you customized AbpClaimsPrincipalFactory or added claim contributors, remove verbose claims or compress/limit them.
  • For React UI, prefer using the Abp Application Configuration endpoint and on-demand authorization checks instead of shipping all permissions in the cookie.

• IIS-specific mitigation (optional)

  • If you must, increase header limits in IIS/ARR. But the sustainable fix is reducing cookie/claims size.

1. Solution Causas típicas por las que tu página deja de respetar los estilos del tema (LeptonX) al usar un layout Blazor personalizado y cómo solucionarlas:

• Falta el wrapper y clases del tema
  • LeptonX aplica la mayor parte del CSS a partir del contenedor con id/clases específicas.
  • Asegúrate de envolver tu layout con:
    • id="lpx-wrapper" y clases como lpx-layout, lpx-content-container, lpx-content, etc.
  • Ejemplo:

<div id="lpx-wrapper" class="lpx-layout lpx-layout--side">
      <MainHeader />
      <div class="lpx-container">
        <SideMenu />
        <div class="lpx-content-container">
          <CustomSubmenu />
          <div class="lpx-topbar-container">
            <div class="lpx-topbar"><Breadcrumbs /></div>
          </div>
          <div class="lpx-content-wrapper">
            <div class="lpx-content">
              <CustomPageActions />
              @Body
            </div>
          </div>
          <footer><Footer /></footer>
        </div>
      </div>
      <MobileNavbar />
    </div>

• No estás usando los componentes de layout del tema

  • Importa y utiliza los componentes de LeptonX del layout que corresponda (SideMenu o TopMenu). Si omites SideMenu/MainHeader/Footer/Breadcrumbs del tema, las clases y estilos asociados no se aplicarán.

• El layout registrado no es el de LeptonX o se reemplazó completamente

  • Verifica en tu módulo que sigas usando el layout del tema (o uno custom basado en él):

Configure<LeptonXThemeBlazorOptions>(options =>
    {
        options.Layout = typeof(Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components
            .ApplicationLayout.SideMenu.SideMenuLayout);
        // o tu CustomApplicationLayout, pero conservando estructura + clases LeptonX
    });

• Falta del bundle de estilos del tema (Blazor WASM/WebApp con Global Assets)

  • En proyectos WASM/WebApp de ABP 9+, el CSS/JS del tema entra por el sistema de bundling global. Asegúrate de:
    • Referenciar el módulo de bundling del tema en el proyecto host (Server/WebApp):
      • Volo.Abp.AspNetCore.Components.WebAssembly.LeptonXTheme.Bundling (o LeptonXLite si usas ese).
    • Llamar app.MapAbpStaticAssets() y usar los módulos de bundling como indica la guía de Global Assets.
  • Si quitaste accidentalmente esos módulos, el CSS del tema no se generará en global.css.

• CSS aislado que sobreescribe variables/clases del tema

  • Un .razor.css con selectores globales o !important puede “romper” el tema. Revisa tus .razor.css y limita el alcance; evita redefinir .lpx-* o variables CSS del tema a menos que sea intencional.

• Mezcla de namespaces de TopMenu y SideMenu

  • No mezcles componentes de TopMenu con clases SideMenu (o viceversa). Usa consistentemente:
    • Side menu: Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.Components.ApplicationLayout.SideMenu.*
    • Top menu: …ApplicationLayout.TopMenu.*

• ¿Debo agregar un CSS al componente?

  • No es obligatorio si usas los componentes + estructura del tema. Normalmente no necesitas CSS adicional; solo añade CSS propio para tu submenu/acciones.
  • Si agregas CSS, hazlo en:
    • global-styles.css incluido vía bundling; o
    • archivos .razor.css específicos sin romper .lpx-*.
  • En WASM/WebApp, si requieres CSS global personalizado, contribúyelo al bundle global (AbpBundlingOptions) para que se incluya en global.css.

Checklist rápido:

• options.Layout apunta al layout correcto y tu CustomApplicationLayout conserva id="lpx-wrapper" y clases lpx-…
• Usas <SideMenu />, <MainHeader />, <Footer />, <Breadcrumbs /> del tema.
• No eliminaste los módulos de bundling del tema; global.css se sirve y app.MapAbpStaticAssets() está activo.
• No tienes CSS propio que sobrescriba .lpx-* de manera no deseada.

1. Solution You don’t have to replace the whole navbar to ask for this to be built into the LeptonX theme. To request product changes (add a persistent, keyboard-accessible collapse/expand button that swaps icons based on state), use ABP Commercial’s official channels below so it’s tracked by the LeptonX team:

What to request

• Always-render a real button for the sidebar toggle (not hover-only), with:
  • type="button", tabindex=0 (native button already focusable)
  • aria-label bound to the action (Expand navigation / Collapse navigation)
  • aria-expanded bound to the current sidebar state
  • Enter/Space to toggle
• Icon swap based on state:
  • Expanded: show “collapse” icon (e.g., bi-filter-left)
  • Collapsed: show “expand” icon (e.g., bi-filter-right)
• Keep hover-trigger behavior, but not as the only way; the button must be present and focusable in both states.
• Expose the state through the theme’s layout service so existing CSS/behavior stays in sync.

How to submit the request

• Open a feature request (or support ticket tagged as “feature request”) describing:
  • Problem: sidebar relies on hover; no keyboard re-expand path.
  • Proposed solution: a persistent, accessible toggle button with ARIA and keyboard handling; icon swaps by state.
  • Acceptance criteria: WCAG 2.1 AA—keyboard operable and correct aria-expanded; no regression to hover behavior.
  • Environment details you already listed (ABP 9.x, Angular LeptonX, tools used).
• Include your screenshots and a suggested HTML/Angular snippet:
  • Example: <button type="button" class="menu-collapse-icon" [attr.aria-label]="isCollapsed ? 'Expand navigation' : 'Collapse navigation'" [attr.aria-expanded]="!isCollapsed" (click)="toggleSidebar()"> <i class="bi" [ngClass]="isCollapsed ? 'bi-filter-right' : 'bi-filter-left'"></i> </button>

Interim workaround (minimal replacement)

• If you want this today without forking theme sources:
  • Use ReplaceableComponentsService to replace only the Navbar component with a small wrapper that adds the button and binds to the theme’s layout state. This keeps upgrades manageable and retains hover behavior because you’ll use the theme’s state service rather than custom state.

1. Solution Here’s a safe, upgrade-friendly way to make the LeptonX Angular left sidebar toggle fully keyboard-accessible while keeping LeptonX’s hover behavior.

A) Use the theme’s replaceable component hook to customize the layout header/toolbar area where the collapse icon lives

• Create your own component that renders an always-focusable button for collapse/expand, exposes ARIA, and handles keyboard.
• Register it as a replaceable component so you don’t patch theme sources.

Example registration (in your ThemeModule or a shared module initialized at app bootstrap):

import { NgModule } from '@angular/core';
import { ReplaceableComponentsService } from '@abp/ng.core';
import { eThemeLeptonXComponents } from '@abp/ng.theme.lepton-x'; // adjust import to your version
import { AccessibleSidebarToggleComponent } from './accessible-sidebar-toggle.component';

@NgModule({
  declarations: [AccessibleSidebarToggleComponent],
  exports: [AccessibleSidebarToggleComponent]
})
export class ThemeCustomizationModule {
  constructor(rc: ReplaceableComponentsService) {
    rc.add({
      key: eThemeLeptonXComponents.Navbar, // or the exact header/toolbar key used by your layout
      component: AccessibleSidebarToggleComponent,
    });
  }
}

B) Implement the toggle component by binding to LeptonX/Theme Shared layout state (do not re-implement state)

• ABP Angular themes keep layout state in a layout service (theme-shared). Use it to get/set “collapsed/expanded” so the rest of the theme stays in sync (CSS classes, hover behavior, etc.).

Example component:

import { Component, HostListener, ChangeDetectionStrategy } from '@angular/core';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';
// Layout service location may differ by version; it’s typically in @abp/ng.theme.shared or @abp/ng.theme.lepton-x
import { LayoutService } from '@abp/ng.theme.shared'; // adjust import path to your version

@Component({
  selector: 'app-accessible-sidebar-toggle',
  template: `
    <button
      type="button"
      class="menu-collapse-icon"
      [attr.aria-label]="(isCollapsed$ | async) ? 'Expand navigation' : 'Collapse navigation'"
      [attr.aria-expanded]="!(isCollapsed$ | async)"
      (click)="toggleSidebar()"
      (keydown)="onKeydown($event)"
    >
      <i class="bi" [ngClass]="(isCollapsed$ | async) ? 'bi-filter-right' : 'bi-filter-left'"></i>
    </button>
  `,
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class AccessibleSidebarToggleComponent {
  // Expose collapsed state from the theme’s layout service
  isCollapsed$: Observable<boolean> = this.layout.state$.pipe(map(s => !!s?.sidebarCollapsed));

  constructor(private layout: LayoutService) {}

  toggleSidebar(): void {
    const cur = this.layout.getState()?.sidebarCollapsed ?? false;
    this.layout.setState({ sidebarCollapsed: !cur });
  }

  onKeydown(e: KeyboardEvent): void {
    if (e.key === 'Enter' || e.key === ' ') {
      e.preventDefault();
      this.toggleSidebar();
    }
  }

  // Optional: expand on focus to mirror hover
  @HostListener('focusin')
  onFocusIn(): void {
    const cur = this.layout.getState()?.sidebarCollapsed ?? false;
    if (cur) {
      this.layout.setState({ sidebarCollapsed: false });
    }
  }
}

Notes:

• The class “menu-collapse-icon” is kept for styling consistency. You can add your own CSS as needed.
• aria-expanded reflects the expanded state of the navigation region (true when sidebar is visible).
• The button remains focusable in both collapsed and expanded states because it’s always rendered.
• The focus handler expands the sidebar when keyboard focus lands on the toggle, matching the hover experience. If you prefer not to auto-expand on focus, remove the HostListener.

C) Keep hover-trigger behavior

• LeptonX uses “hover-trigger” to expand when collapsed on mouse hover. Do not remove that behavior; by using the theme’s layout state, hover-trigger will continue to work. Your button simply adds keyboard and ARIA on top of it.

D) Where to place the toggle

• If the original collapse icon is inside the layout’s Navbar/Toolbar area, replacing the Navbar replaceable component is typically the right extension point.
• If your app uses SideMenuLayoutModule or TopMenuLayoutModule variants, ensure you register the replacement in a module that’s loaded with your chosen layout, and use the correct key from eThemeLeptonXComponents for that layout version.

E) Persisting user choice (optional)

• If you want the collapsed state to persist, subscribe to the state$ and store sidebarCollapsed in localStorage, then initialize the LayoutService state on app start accordingly:

// On app init
const saved = localStorage.getItem('sidebarCollapsed') === 'true';
layout.setState({ sidebarCollapsed: saved });

// When state changes
layout.state$.subscribe(s => localStorage.setItem('sidebarCollapsed', String(!!s?.sidebarCollapsed)));

F) Minimal template-only alternative

• If you prefer not to replace the whole Navbar, you can still add a focusable button near the existing icon by creating a small component projected into a replaceable region (if your version exposes such a slot). The essential parts remain: role=button (native button), aria-expanded, Enter/Space handling, and binding to the LayoutService.
