Is there a way to have a list where each item has an optional dropdown, that overlaps the list items below it?

I am trying to make a list of Entry fields that is loaded N times, with some text and comments together.
This is my layout
And when the text is typed I am trying to make a suggestion of text back from a predefined text collection but, the suggestion layout push all the controls below but not get over top.
This is how the suggested text will look like
I tried using absolute layout but actually cannot get what I am wanting. Each Enter Text has its suggestion and since there can be N times. So I want to fix it for all some text. And all have different text suggestion length.

</Grid>
</Frame>
</DataTemplate>

</StackLayout>
I have tried different combination of Absolute Layout's LayoutFlags and LayoutBounds but cannot achieve what I want. Can any one how can I achieve it? If it is possible using something other than absolute layout then please suggest.

What can I do to show the shadow all around the frame? Please help and thanks.
EDIT
This is what I have with Margin=2 on Frame
Margin=50
Padding=50
Just to show how it behaves

At first, you can create a new frame in your project to check if the cause is the renderer or not. Such as:
<Frame Margin="20" CornerRadius="10" HasShadow="True">
<Label Text="TestShaw" HorizontalOptions="Center"/>
</Frame>
If the shadow shows correctly, the cause maybe the layout or the margin of your frame. So you can change the values of it.
If the shadow shows incorrectly too, you may need to use a custom renderer for the frame. Such as:
[assembly: ExportRenderer(typeof(Myframe), typeof(MyFrameRenderer))]
namespace App36.Droid
{
public class MyFrameRenderer : Xamarin.Forms.Platform.Android.FastRenderers.FrameRenderer
{
public MyFrameRenderer(Context context) : base(context)
{
}
protected override void OnElementChanged(ElementChangedEventArgs<Frame> e)
{
base.OnElementChanged(e);
CardElevation = 50;
SetOutlineSpotShadowColor(Xamarin.Forms.Color.Black.ToAndroid());
SetOutlineAmbientShadowColor(Xamarin.Forms.Color.Black.ToAndroid());
}
}
}
But in my project, both of them shows correctly. So if you need more information, you can check the link following.
Link: Xamarin forms Shadow on Frame in Android
And here is the frame in my project:
If the platform is ios for your project, please check this case:Forms frame isn't the same on iOS

There are plenty of samples and controls out there. You don't really need to do it yourself. Syncfusion offers some nice controls for Xamarin. There is a free Community License too.
I think that's what you want -> https://www.syncfusion.com/products/xamarin
