This section briefly explains about how to include Blazor Tabs component in your Blazor Server App and Blazor WebAssembly App using Visual Studio.
To get start quickly with Blazor Tabs, you can check on this video or GitHub sample:
Prerequisites
Create a new Blazor App in Visual Studio
You can create a Blazor Server App or Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Syncfusion Blazor Extension.
Install Syncfusion Blazor Navigations and Themes NuGet in the App
To add Blazor Tabs component in the app, open the NuGet package manager in Visual Studio (Tools β NuGet Package Manager β Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.Navigations and Syncfusion.Blazor.Themes. Alternatively, you can utilize the following package manager command to achieve the same.
Install-Package Syncfusion.Blazor.Navigations -Version 27.1.48
Install-Package Syncfusion.Blazor.Themes -Version 27.1.48
NOTE
Syncfusion Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.
Register Syncfusion Blazor Service
Open ~/_Imports.razor file and import the Syncfusion.Blazor
and Syncfusion.Blazor.Navigations
namespace.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Navigations
Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Server App or Blazor WebAssembly App.
using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor();
var app = builder.Build();
....
using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;
var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");
builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();
....
Add stylesheet and script resources
The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Reference the stylesheet and script in the <head>
of the main page as follows:
-
For .NET 6 Blazor Server app, include it in ~/Pages/_Layout.cshtml file.
-
For .NET 7 Blazor Server app, include it in the ~/Pages/_Host.cshtml file.
-
For Blazor WebAssembly app, include it in the ~/index.html file.
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</head>
NOTE
Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.
Add Blazor Tabs component
Add the Syncfusion Blazor Tabs component in the ~/Pages/Index.razor file.

<div>HyperText Markup Language, commonly referred to as HTML, is the standard markup language used to create web pages. Along with CSS, and JavaScript, HTML is a cornerstone technology, used by most websites to create visually engaging web pages, user interfaces for web applications, and user interfaces for many mobile applications.[1] Web browsers can read HTML files and render them into visible or audible web pages. HTML describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language.</div>
