FrameView.xaml

 <Frame x:Name="frame" HasShadow="True" >
            <StackLayout x:Name="sl" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
                <Grid HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"></ColumnDefinition>
                        <ColumnDefinition Width="Auto"></ColumnDefinition>
                    </Grid.ColumnDefinitions>
                    <Label x:Name="lblName" Grid.Column="0" FontAttributes="Bold" HorizontalOptions="FillAndExpand" 
                           VerticalOptions="FillAndExpand" TextColor="Black" >
                        <Label.GestureRecognizers>
                            <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"></TapGestureRecognizer>
                        </Label.GestureRecognizers>
                    </Label>
                    <Label x:Name="lblIcon" Grid.Column="1" FontFamily="{StaticResource FontAwesomeSolid}" 
                            Text="{x:Static fontawesome:Regular.Angle_Up}" HorizontalOptions="FillAndExpand" 
                           VerticalOptions="Start" FontAttributes="Bold" TextColor="Black">
                        <Label.GestureRecognizers>
                            <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"></TapGestureRecognizer>
                        </Label.GestureRecognizers>
                    </Label>
                </Grid>

                <Frame Padding="10"  BackgroundColor="White" x:Name="ContentFrame" HasShadow="False">
                </Frame>
            </StackLayout>
        </Frame>  

FrameView.cs

  public FrameView()
        {
            InitializeComponent();
            frame.HeightRequest =  lblName.Height;
        }

        public string Text
        {
            get
            {
                return lblName.Text;
            }
            set
            {
                lblName.Text = value;
            }
        }

        public View ContainerContent
        {
            get
            {
                return ContentFrame.Content;
            }
            set
            {
                ContentFrame.Content = value;
            }
        }

        private void TapGestureRecognizer_Tapped(object sender, EventArgs e)
        {
            ContentFrame.IsVisible = !ContentFrame.IsVisible;
            lblIcon.Text = ContentFrame.IsVisible ? Regular.Angle_Up : Regular.Angle_Down;
        }
