You could try using a Bindable Layout with a nested CollectionView or ListView, this would allow you to use a List of Lists for your data bindings.

it could look something like this;

public class MyNestedListItem {
    
    public MyNestedListItem(string myTest)  {
        MyText = myText;
    }

    public string MyText { get; set; }
}


public class MyList {

    public MyList(string listName, list<MyNestedListItem> myNestedList) {
        ListName = listName;
        MyNestedList = myNestedList; 
    }
    
    public string ListName { get; set; }
    public List<MyNestedListItem> MyNestedList { get; set; }
}


public class MyViewModel {
    
    public ObservableCollection<MyList> MyList { get; set }

    public MyViewModel() {

        var nestedListA = new List<MyNestedListItem> 
        { 
            new MyNestedListItem("A1"); 
            new MyNestedListItem("A2"); 
            new MyNestedListItem("A3"); 
        }

        var nestedListB = new ...;


        MyList = new ObservableCollection<MyList> {
            new MyList("List A", nestedListA);
            new MyList("List B", nestedListB);
        } 
    }
}

XAML

<StackLayout Orientation="Horizontal"
        VerticalOptions="Start"
        HorizontalOptions="Center"
        BindableLayout.ItemsSource="{Binding MyList}">
<BindableLayout.ItemTemplate>
    <DataTemplate>
        <Frame WidthRequest="75" 
            HeightRequest="25"
            CornerRadius="25"
            Padding="0"
            HasShadow="True">
        <Label Text="{Binding ListName }"
            <CollectionView ItemsSource="{Binding MyNestedList }" 
                VerticalOptions="Center"
                HorizontalOptions="Center">
            <CollectionView.ItemTemplate>
                <DataTemplate>
                    <StackLayout>
                    < ..... your layout stuff here />
                    </StackLayout>
                </DataTemplate>
            </CollectionView>
        </Frame>
    </DataTemplate>
</BindableLayout.ItemTemplate>

This could be a good starting point to achieve a nested list

You can use a two-row and four-column Grid inside the listview to avoid nested lists.

It can be easier to implement your page style.
