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 first. If the solution is tiered/micro-service, complete the MVC steps for all MVC applications such as HttpApi.Host and AuthServer.
Add Volo.Abp.AspNetCore.Components.Server.LeptonXLiteTheme package to your Blazor server application with the following command:
```
dotnet add package Volo.Abp.AspNetCore.Components.Server.LeptonXLiteTheme --prerelease
```
Remove Volo.Abp.AspNetCore.Components.Server.BasicTheme reference from the project since it's not necessary after switching to LeptonX Lite.

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

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

    // Add LeptonX Lite module to DependsOn attribute
+    typeof(AbpAspNetCoreComponentsServerLeptonXLiteThemeModule)
)]

Replace BlazorBasicThemeBundles with BlazorLeptonXLiteThemeBundles in AbpBundlingOptions:

options.StyleBundles.Configure(
  // Remove following line
- BlazorBasicThemeBundles.Styles.Global,
  // Add following line instead
+ BlazorLeptonXLiteThemeBundles.Styles.Global,
  bundle =>
  {
      bundle.AddFiles("/blazor-global-styles.css");
      //You can remove the following line if you don't use Blazor CSS isolation for components
      bundle.AddFiles("/MyProjectName.Blazor.styles.css");
  });

Update _Host.cshtml file. (located under Pages folder by default.)

Add following usings to Locate App and BlazorLeptonXLiteThemeBundles classes.

@using Volo.Abp.AspNetCore.Components.Web.LeptonXLiteTheme.Themes.LeptonXLite
@using Volo.Abp.AspNetCore.Components.Server.LeptonXLiteTheme.Bundling

Then replace script & style bundles as following:

// Remove following line
- <abp-style-bundle name="@BlazorBasicThemeBundles.Styles.Global" />
// Add following line instead
+ <abp-style-bundle name="@BlazorLeptonXLiteThemeBundles.Styles.Global" />

// Remove following line
- <abp-script-bundle name="@BlazorBasicThemeBundles.Scripts.Global" />
// Add following line instead
+ <abp-script-bundle name="@BlazorLeptonXLiteThemeBundles.Scripts.Global" />

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

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!

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;
}

You can visit the Toolbars Documentation for better understanding.

Components

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.

Branding Component

The branding component is a simple component that can be used to display your brand. It contains a logo and a company name.

How to Override Branding Component

Create a razor page, like MyBrandingComponent.razor, in your blazor application as shown below:

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

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

@Name

If you prefer to use a code-behind file for the C# code of your component, create a razor component, like MyBrandingComponent.razor.cs, in your blazor application as shown below:

namespace LeptonXLite.DemoApp.Blazor.MyComponents
{
    public partial class MyBrandingComponent
    {
        public string Name = "My Branding Component";
    }
}

How to override the favicon

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

If you prefer to use a code-behind file for the C# code of your component, create a razor component, like MyBreadcrumbsComponent.razor.cs, in your blazor application as shown below:

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";
    }
}

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

    [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.

    {
        public string Name = "My Toolbar Items Component";
    }
}
