UI

LeptonX Lite Blazor UI

LeptonX Lite has implementation for the ABP Framework Blazor WebAssembly & Blazor Server. It's a simplified variation of the LeptonX Theme.

If you are looking for a professional, enterprise ready theme, you can check the LeptonX Theme, which is a part of ABP Commercial.

See the Theming document to learn about themes.

Installation

This theme is already installed when you create a new solution using the startup templates. If you are using any other template, you can install this theme by following the steps below:

  • Complete the MVC Razor Pages Installation for the HttpApi.Host application first. If the solution is tiered/micro-service, complete the MVC steps for all MVC applications such as HttpApi.Host and if Auth Server is separated, install to the OpenIddict.

  • Add Volo.Abp.AspNetCore.Components.WebAssembly.LeptonXLiteTheme package to your Blazor WebAssembly application with the following command:

    dotnet add package Volo.Abp.AspNetCore.Components.WebAssembly.LeptonXLiteTheme --prerelease
    
  • Remove Volo.Abp.AspNetCore.Components.WebAssembly.BasicTheme reference from the project since it's not necessary after switching to LeptonX Lite.

  • Remove the old theme from the DependsOn attribute in your module class and add the AbpAspNetCoreComponentsWebAssemblyLeptonXLiteThemeModule type to the DependsOn attribute.

[DependsOn(
     // Remove BasicTheme module from DependsOn attribute
-    typeof(AbpAspNetCoreComponentsWebAssemblyBasicThemeModule),

    // Add LeptonX Lite module to DependsOn attribute
+    typeof(AbpAspNetCoreComponentsWebAssemblyLeptonXLiteThemeModule),
)]
  • Change startup App component with the LeptonX one.
// Make sure the 'App' comes from 'Volo.Abp.AspNetCore.Components.Web.LeptonXLiteTheme.Themes.LeptonXLite' namespace.
builder.RootComponents.Add<App>("#ApplicationContainer");
  • Run the abp bundle command in your Blazor application folder.

Customization

Layout

  • Create a razor page, like MyMainLayout.razor, in your blazor application as shown below:
@using Volo.Abp.AspNetCore.Components.Web.LeptonXLiteTheme.Themes.LeptonXLite;
@using Volo.Abp.DependencyInjection

@inherits MainLayout
@attribute [ExposeServices(typeof(MainLayout))]
@attribute [Dependency(ReplaceServices = true)]

@Name

@code {
    string Name = "My Main Layout";
}
  • If you prefer to use a code-behind file for the C# code of your component, create a razor component, like MyMainLayout.razor.cs, in your blazor application as shown below:
[ExposeServices(typeof(MainLayout))]
[Dependency(ReplaceServices = true)]
namespace LeptonXLite.DemoApp.Blazor.MyComponents
{
    public partial class MyMainLayout
    {
        public string Name = "My Main Layout";
    }
}

Don't forget to remove the repeated attributes from the razor page! Don't forget to remove the @code section from the razor page!

Toolbars

LeptonX Lite includes separeted toolbars for desktop & mobile. You can manage toolbars independently. Toolbar names can be accessible in the LeptonXLiteToolbars class.

  • LeptonXLiteToolbars.Main
  • LeptonXLiteToolbars.MainMobile
public async Task ConfigureToolbarAsync(IToolbarConfigurationContext context)
{
    if (context.Toolbar.Name == LeptonXLiteToolbars.Main)
    {
        context.Toolbar.Items.Add(new ToolbarItem(typeof(MyDesktopComponent)));
    }

    if (context.Toolbar.Name == LeptonXLiteToolbars.MainMobile)
    {
        context.Toolbar.Items.Add(new ToolbarItem(typeof(MyMobileComponent)));
    }

    return Task.CompletedTask;
}

LeptonX Blazor is built on the basis of components. You can use the components in your application as you wish, or you can customize the components by overriding them. If you want to override a component please follow the steps.

@attribute [ExposeServices(typeof(Branding))]

    {
        public string Name = "My Branding Component";

Startup templates contain favicon.ico files under the wwwroot folder of the Blazor application. You can change this file to override the current favicon.

Breadcrumb Component

On websites that have a lot of pages, breadcrumb navigation can greatly enhance the way users find their way around. In terms of usability, breadcrumbs reduce the number of actions a website visitor needs to take in order to get to a higher-level page, and they improve the findability of website sections and pages.

How to Override the BreadCrumb Component

  • Create a razor page, like MyBreadcrumbsComponent.razor, in your blazor application as shown below:
@using Volo.Abp.AspNetCore.Components.Web.LeptonXLiteTheme.Themes.LeptonXLite;
@using Volo.Abp.DependencyInjection

@inherits Breadcrumbs
@attribute [ExposeServices(typeof(Breadcrumbs))]
@attribute [Dependency(ReplaceServices = true)]

@Name

@code {
    string Name = "My Breadcrumbs Component";
}

using Volo.Abp.AspNetCore.Components.Web.LeptonXLiteTheme.Themes.LeptonXLite;
using Volo.Abp.DependencyInjection;

namespace LeptonXLite.DemoApp.Blazor.MyComponents
{
    [ExposeServices(typeof(Breadcrumbs))]
    [Dependency(ReplaceServices = true)]
    public partial class MyBreadcrumbsComponent
    {
        public string Name = "My Breadcrumbs Component";
    }
}

Main Menu Component

Sidebar menus have been used as a directory for Related Pages for a Service offering, Navigation items for a specific service or topic and even just as Links the user may be interested in.

How to Override the Main Menu Component

  • Create a razor page, like MyMainMenuComponent.razor, in your blazor application as shown below:
@using Volo.Abp.AspNetCore.Components.Web.LeptonXLiteTheme.Themes.LeptonXLite.Navigation;
@using Volo.Abp.DependencyInjection

@inherits MainMenu
@attribute [ExposeServices(typeof(MainMenu))]
@attribute [Dependency(ReplaceServices = true)]

@Name

@code {
    string Name = "My Main Menu Component";
}
  • If you prefer to use a code-behind file for the C# code of your component, create a razor component, like MyMainMenu.razor.cs, in your blazor application as shown below:

    [Dependency(ReplaceServices = true)]
    public partial class MainMenu
    {
        public string Name = "My Main Menu Component";
    }
}

The main menu renders the menu items dynamically. The menu item is a razor component named MainMenuItem.razor.cs in the same namespace with main menu and you can override it like the main menu.
