This article provides a step-by-step instructions for building Blazor Web App with Blazor Accordion component using Visual Studio.

Using Playground

Blazor Playground allows you to interact with our Blazor components directly in your web browser without need to install any required NuGet packages. By default, the Syncfusion.Blazor package is included in this.

To use the individual component in Blazor playground, uninstall the existing package and then install the needed NuGet package.

System requirements for Blazor components

Using Syncfusion Blazor Template

Run the following command to create a new Blazor Web App in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

If you set the Authentication Type as None and Interactivity location as Per page/component, you need to use the following command.

Interactive Render Mode	Command
Server	C# `dotnet new blazor -o BlazorApp -int Server`
WebAssembly	C# `dotnet new blazor -o BlazorApp -int WebAssembly`
Auto	C# `dotnet new blazor -o BlazorApp -int Auto`
None	C# `dotnet new blazor -o BlazorApp -int None`

If you set the Authentication Type as Individual Accounts and Interactivity location as Per page/component, you need to use the following command.

Interactive Render Mode	Command
Server	C# `dotnet new blazor -o BlazorApp -au Individual -int Server`
WebAssembly	C# `dotnet new blazor -o BlazorApp -au Individual -int WebAssembly`
Auto	C# `dotnet new blazor -o BlazorApp -au Individual -int Auto`
None	C# `dotnet new blazor -o BlazorApp -au Individual -int None`

If you set the Authentication Type as Individual Accounts and Interactivity location as Global, you need to use the following command.

Interactive Render Mode	Command
Server	C# `dotnet new blazor -o BlazorApp -au Individual -int Server -ai`
WebAssembly	C# `dotnet new blazor -o BlazorApp -au Individual -int WebAssembly -ai`
Auto	C# `dotnet new blazor -o BlazorApp -au Individual -int Auto -ai`
None	C# `dotnet new blazor -o BlazorApp -au Individual -int None -ai`

If you set the Authentication Type as None and Interactivity location as Global, you need to use the following command.

Interactive Render Mode	Command
Server	C# `dotnet new blazor -o BlazorApp -int Server-ai`
WebAssembly	C# `dotnet new blazor -o BlazorApp -int WebAssembly -ai`
Auto	C# `dotnet new blazor -o BlazorApp8 -int Auto -ai`
None	C# `dotnet new blazor -o BlazorApp8 -int None -ai`

NOTE

If you want to see more available templates, you need to run the dotnet new blazor --help or dotnet new blazor -h command.

Manually Creating a project

Create a new Blazor Web App

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion Blazor Extension.

You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.

Install Syncfusion Blazor Navigations and Themes NuGet in the Blazor Web App

Here’s an example of how to add Blazor Accordion 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.

If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion Blazor components NuGet packages within the client project.

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 .

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Navigations

Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Web App. For a app with WebAssembly or Auto (Server and WebAssembly) interactive render mode, register the Syncfusion Blazor service in both ~/Program.cs files of your web app.

....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>

<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

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 Syncfusion Blazor Accordion component

Add the Syncfusion Blazor Accordion component in the ~/Components/Pages/*.razor file. If an interactivity location as Per page/component in the web app, define a render mode at the top of the ~Pages/*.razor component, as follows:

RAZOR

@* desired render mode define here *@
@rendermode InteractiveAuto
