This section briefly explains about how to include Blazor Menu Bar component in your Blazor Server App and Blazor WebAssembly App using Visual Studio.

To get started quickly with Menu Bar Component using Blazor, you can check on this video or GitHub sample.

Prerequisites

System requirements for Blazor components

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 Menu Bar component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → 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.

Package Manager
Install-Package Syncfusion.Blazor.Navigations -Version 25.1.35
Install-Package Syncfusion.Blazor.Themes -Version 25.1.35

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.

~/_Imports.razor

@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.

Blazor Server App
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 the Syncfusion Blazor Menu Bar component in the ~/Pages/Index.razor file.

RAZOR
<SfMenu TValue="MenuItem">
    <MenuItems>
        <MenuItem Text="File">
            <MenuItems>
                <MenuItem Text="Open"></MenuItem>
                <MenuItem Text="Save"></MenuItem>
                <MenuItem Text="Exit"></MenuItem>
            </MenuItems>
        </MenuItem>
        <MenuItem Text="Edit">
            <MenuItems>
                <MenuItem Text="Cut"></MenuItem>
                <MenuItem Text="Copy"></MenuItem>
                <MenuItem Text="Paste"></MenuItem>
            </MenuItems>
        </MenuItem>
        <MenuItem Text="View">
            <MenuItems>
                <MenuItem Text="Toolbars"></MenuItem>
                <MenuItem Text="Zoomr"></MenuItem>
                <MenuItem Text="Full Screen"></MenuItem>
            </MenuItems>
        </MenuItem>
        <MenuItem Text="Tools">
            <MenuItems>
                <MenuItem Text="Spelling & Grammar"></MenuItem>
                <MenuItem Text="Customize"></MenuItem>
                <MenuItem Text="Options"></MenuItem>
            </MenuItems>
        </MenuItem>
        <MenuItem Text="Go"></MenuItem>
        <MenuItem Text="Help"></MenuItem>
    </MenuItems>
</SfMenu>

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion Blazor Menu Bar component in your default web browser.

NOTE

TValue can be specified as either MenuItemModel or MenuItem. If the menu is generated using the Items property, then TValue is specified as MenuItemModel. However, if it is created using a tag directive, then TValue is specified as MenuItem.
