Step 1: Add the NuGet to the project and add the namespace as shown in the following code sample:

[XAML]

xmlns:buttons="clr-namespace:Syncfusion.XForms.Buttons;assembly=Syncfusion.Buttons.XForms"

[C#]

using Syncfusion.XForms.Buttons;

Step 2: Then initialize an empty SfChipGroup as shown in the following code:

[XAML]

<ContentPage.Content>
  <Grid>
     <buttons:SfChipGroup/>
  </Grid>
</ContentPage.Content>

[C#]

public GettingStarted()
{
  InitializeComponent();
  Grid grid = new Grid();
  grid.Children.Add(new SfChipGroup());
  this.Content = grid;
}

Allows users to select more than one chip in a group of chips. The selected chips are indicated by selection indicator in this type. The selection indicator can be customized using the SelectionIndicatorColorproperty. Use the SelectedItems property to get the list of selected chips.

This selection changes are notified by using SelectionChanging and SelectionChanged events.

The following code illustrates how to get filter typed ChipGroup.

[XAML]

<buttons:SfChipGroup 
	Type="Filter"   
	ItemsSource="{Binding Languages}"
	SelectedChipBackgroundColor="Red"
	ChipPadding="8,8,0,0" 
	SelectionIndicatorColor="White"
	DisplayMemberPath="Name">
	<buttons:SfChipGroup.ChipLayout>
		<FlexLayout 
			HorizontalOptions="Start" 
			VerticalOptions="Center" 
			Direction="Row" 
			Wrap="Wrap"
			JustifyContent="Start"
			AlignContent="Start" 
			AlignItems="Start"/>
	</buttons:SfChipGroup.ChipLayout>
</buttons:SfChipGroup>

[ViewModel]

public class ViewModel : INotifyPropertyChanged
{
	private ObservableCollection<Language> languages;

	...

	public event PropertyChangedEventHandler PropertyChanged;

	public ObservableCollection<Language> Languages
	{
		get
		{
			return languages;
		}
		set
		{
			languages = value;
			PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("Languages"));
		}
	}
	
	...

	public ViewModel()
	{
		Languages = new ObservableCollection<Language>();
		Languages.Add(new Language() { Name = "C#" });
		Languages.Add(new Language() { Name = "HTML" });
		Languages.Add(new Language() { Name = "Java" });
		Languages.Add(new Language() { Name = "JS" });
      ...
	}
}

[Language Model]

public class Language
{
	public string Name { get; set; }
}
