This section guides you through setting up and configuring a Accordion in your .NET MAUI application. Follow the steps below to add a basic Accordion to your project.

To quickly get started with the .NET MAUI Accordion, watch this video:

Prerequisites

Before proceeding, ensure the following are set up:

  1. Install .NET 9 SDK or later.
  2. Set up a .NET MAUI environment with Visual Studio 2022 v17.12 or later.

Step 1: Create a new .NET MAUI Project

  1. Go to File > New > Project and choose the .NET MAUI App template.
  2. Name the project and choose a location. Then, click Next.
  3. Select the .NET framework version and click Create.

Step 2: Install the Syncfusion® MAUI Expander NuGet Package

  1. In Solution Explorer, right-click the project and choose Manage NuGet Packages.
  2. Search for Syncfusion.Maui.Expander and install the latest version.
  3. Ensure the necessary dependencies are installed correctly, and the project is restored.

Step 3: Register the handler

Syncfusion.Maui.Core NuGet is a dependent package for all Syncfusion® controls of .NET MAUI. In the MauiProgram.cs file, register the handler for Syncfusion® core.

  • C#
    • using Syncfusion.Maui.Core.Hosting;

namespace GettingStarted
{
    public class MauiProgram 
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                });

            builder.ConfigureSyncfusionCore();
            return builder.Build();
        }
    }
}

    Step 4: Add a Basic Accordion

    1. To initialize the control, import the Syncfusion.Maui.Accordion namespace into your code.
    2. Initialize SfAccordion.
    <ContentPage   
    . . .
    xmlns:syncfusion="clr-namespace:Syncfusion.Maui.Accordion;assembly=Syncfusion.Maui.Expander">

    <syncfusion:SfAccordion />
</ContentPage>
    using Syncfusion.Maui.Accordion;
. . .
public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        SfAccordion accordion = new SfAccordion();
    }
}

namespace GettingStarted
{
    public class MauiProgram 
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                });

            builder.ConfigureSyncfusionCore();
            return builder.Build();

    <syncfusion:SfAccordion />
</ContentPage>
    using Syncfusion.Maui.Accordion;
. . .
public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        SfAccordion accordion = new SfAccordion();
    }
}

    Prerequisites

    Before proceeding, ensure the following are set up:

    1. Install .NET 9 SDK or later.
    2. Set up a .NET MAUI environment with JetBrains Rider 2024.3 or later.
    3. Make sure the MAUI workloads are installed and configured as described here.

    Step 1: Create a new .NET MAUI Project

    1. Go to File > New Solution, Select .NET (C#) and choose the .NET MAUI App template.

    3. Ensure the necessary dependencies are installed correctly, and the project is restored. If not, Open the Terminal in Rider and manually run: dotnet restore

    Step 3: Register the handler

    Syncfusion.Maui.Core NuGet is a dependent package for all Syncfusion® controls of .NET MAUI. In the MauiProgram.cs file, register the handler for Syncfusion® core.

  • C#
    • using Syncfusion.Maui.Core.Hosting;

namespace GettingStarted
{
    public class MauiProgram 
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                });

            builder.ConfigureSyncfusionCore();
            return builder.Build();
        }
    }
}

    Step 4: Add a Basic Accordion

    1. To initialize the control, import the Syncfusion.Maui.Accordion namespace into your code.
    2. Initialize SfAccordion.
    <ContentPage   
    . . .
      xmlns:syncfusion="clr-namespace:Syncfusion.Maui.Accordion;assembly=Syncfusion.Maui.Expander">
    <syncfusion:SfAccordion />
</ContentPage>
    using Syncfusion.Maui.Accordion;
. . .
public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        SfAccordion accordion = new SfAccordion();
    }
}

    Step 5: Define the accordion items

    Create the AccordionItem instance that comprise a header & content and add it into Items of SfAccordion.

    In this example, a Grid is loaded in both the header and content of accordion items.

    NOTE

    When loading Label as direct children of Header or Content of AccordionItem, then it will lead to an exception. So, load Label inside Grid to overcome the crash.

    <syncfusion:SfAccordion x:Name="accordion">
    <syncfusion:SfAccordion.Items>
        <syncfusion:AccordionItem>
            <syncfusion:AccordionItem.Header>
                <Grid HeightRequest="48">
                    <Label Text="Robin Rane"
                           FontSize="14" />
                </Grid>
            </syncfusion:AccordionItem.Header>
            <syncfusion:AccordionItem.Content>
                <Grid BackgroundColor="#f4f4f4"
                      Padding="10"
                      RowSpacing="10"
                      ColumnSpacing="15"
                      RowDefinitions="Auto,Auto,Auto"
                      ColumnDefinitions="120,*">
                    <Image Source="emp_01.png"
                           Grid.Row="0"
                           Grid.Column="0"
                           Grid.RowSpan="1"
                           HeightRequest="100"
                           WidthRequest="100" />
                    <StackLayout Grid.Row="0"
                                 Grid.Column="1"
                                 Spacing="8">
                        <Label Text="Position: Chairman"

                           Text="Robin Rane, Chairman of ABC Inc., leads with dedication and vision. Under his guidance, the company thrives and continues to make a significant impact in the industry."
                           FontSize="12"
                           LineBreakMode="WordWrap" />
                    <Label Grid.Row="2"
                           Grid.Column="0"
                           Grid.ColumnSpan="2"
                           Text="Phone: (617) 555-1234"
                           FontSize="12" />

        };

        headerGrid.Children.Add(new Label
        {
            Text = "Robin Rane",
            FontSize = 14
        });

        return headerGrid;
    }

    private View CreateContent()
    {
        var contentGrid = new Grid
        {
            BackgroundColor = Color.FromArgb("#f4f4f4"),
            Padding = 10,

    }
}

    The following screenshot illustrates the result of the above code.

    Defining the Accordion items

    You can download accordion sample for .NET MAUI here.

    NOTE

    When adding the template control inside the Grid with a height set to Auto, the child element will not receive the height changes at runtime. Since the SfAccordion is a template-based control, the default height value cannot be determined. Therefore, it is recommended to provide the HorizontalOptions and VerticalOptions as FillAndExpand options for the control.

    NOTE

    You can refer to our .NET MAUI Accordion feature tour page for its groundbreaking feature representations. You can also explore our .NET MAUI Accordion Example that shows you how to render and configure the Accordion in .NET MAUI.
