Getting Started with MAUI Accordion

20 Sep 202419 minutes to read

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 in place:

  1. Install .NET 7 SDK or later.
  2. Set up a .NET MAUI environment with Visual Studio 2022 (v17.3 or later) or VS Code. For VS Code users, ensure that the .NET MAUI workload is installed and configured as described here.

Step 1: Create a .NET MAUI project

Visual Studio

  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. Then, click Create.

Visual Studio Code

  1. Open the command palette by pressing Ctrl+Shift+P and type .NET:New Project and Enter.
  2. Choose the .NET MAUI App template.
  3. Select the project location, type the project name and press Enter.
  4. Then choose Create Project.

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

The Syncfusion.Maui.Core is a dependent package for all Syncfusion controls in .NET MAUI. In the MauiProgram.cs file, you need to register the handler for Syncfusion core.

using Microsoft.Maui.Controls.Hosting;
using Microsoft.Maui.Controls.Xaml;
using Microsoft.Maui.Hosting;
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.

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:GettingStarted"
             x:Class="GettingStarted.MainPage"
             xmlns:syncfusion="clr-namespace:Syncfusion.Maui.Accordion;assembly=Syncfusion.Maui.Expander">
<ContentPage.Content>
        <syncfusion:SfAccordion >
            <syncfusion:SfAccordion.Items>
                <syncfusion:AccordionItem>
                    <syncfusion:AccordionItem.Header>
                        <Grid  HeightRequest="48">
                            <Label Text="Robin Rane" Margin="16,14,0,14" CharacterSpacing="0.25" FontFamily="Roboto-Regular"  FontSize="14" />
                        </Grid>
                    </syncfusion:AccordionItem.Header>
                    <syncfusion:AccordionItem.Content>
                        <Grid ColumnSpacing="10" RowSpacing="2" BackgroundColor="#f4f4f4"  >
                            <Grid Margin="16,6,0,0">
                                <Grid.Resources>
                                    <Style TargetType="Label">
                                        <Setter Property="FontFamily" Value="Roboto-Regular"/>
                                    </Style>
                                </Grid.Resources>
                                <Grid.RowDefinitions >
                                    <RowDefinition Height="25"/>
                                    <RowDefinition Height="25"/>
                                    <RowDefinition Height="25"/>

                                    <RowDefinition Height="{OnPlatform Default=90,Android=90,WinUI=70, iOS=100,MacCatalyst=70 }"/>
                                    <RowDefinition Height="Auto"/>
                                </Grid.RowDefinitions>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="100"/>

                        </Grid>
                    </syncfusion:AccordionItem.Content>
                </syncfusion:AccordionItem>
                ..........................
            </syncfusion:SfAccordion.Items>
        </syncfusion:SfAccordion>
    </ContentPage.Content>
</ContentPage>

Step 6: Running the Application

Press F5 to build and run the application. Once compiled, the Accordion will be displayed with the data provided.

Here is the result of the previous codes,

.NET MAUI Accordion with items

You can download accordion sample for .NET MAUI here.

NOTE

When adding the template control inside the StackLayout or 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.

Animation duration

The SfAccordion allows you to customize the expanding and collapsing duration of accordion items by using the AnimationDuration property. By default, the animation duration is set to 200 milliseconds.

<syncfusion:SfAccordion x:Name="accordion" 
                            AnimationDuration="150" />
accordion.AnimationDuration = 150;

Animation easing

You can customize the rate of change of a parameter over time or the animation style of an accordion item by using the AnimationEasing property. By default, the animation easing is set to Linear.

<syncfusion:SfAccordion x:Name="accordion"
                                AnimationEasing="SinOut" />
accordion.AnimationEasing = ExpanderAnimationEasing.SinOut;

Auto scroll position

The SfAccordion allows you to customize the scroll position of the expanded accordion item using the AutoScrollPosition property. By default, the auto-scroll position is set to MakeVisible.

<syncfusion:SfAccordion x:Name="accordion"
                             AutoScrollPosition="Top"/>
accordion.AutoScrollPosition = AccordionAutoScrollPosition.Top;

Bring an accordion item into view

The BringIntoView method is used to bring a specific item into view by scrolling to it programmatically.

<syncfusion:SfAccordion x:Name="accordion">
    <syncfusion:SfAccordion.Items>
        <syncfusion:AccordionItem>
            ...
            ...
        </syncfusion:AccordionItem>
    </syncfusion:SfAccordion.Items>
 </syncfusion:SfAccordion>
private void Button_Clicked(object sender, EventArgs e)
{
    accordion.BringIntoView(accordion.Items[15]);
}

Expand mode

You can expand single or multiple items using the ExpandMode property. By default, the expanded mode is set to Single.

<syncfusion:SfAccordion x:Name="accordion" 
                            ExpandMode="Multiple" />
accordion.ExpandMode = AccordionExpandMode.Multiple;

Item spacing

The SfAccordion allows you to customize the vertical spacing between the accordion items by using the ItemSpacing property.

<syncfusion:SfAccordion x:Name="accordion" 
                            ItemSpacing="6.0d" />
accordion.ItemSpacing = 6.0d;
