How to hide “no items” of CompletionSession?

Hello,

You can alter the appearance of the "no items" UI.  The IntelliPromptCompletionList primitive control has a NoItemsTemplate property that is currently set this way:

<Setter Property="NoItemsTemplate">
	<Setter.Value>
		<DataTemplate>

			<Border Background="{DynamicResource {x:Static themes:AssetResourceKeys.ListBackgroundNormalBrushKey}}" Padding="4,1">
				<TextBlock Text="{productsEditor:SRExtension UIIntelliPromptCompletionListNoItemsText}" FontStyle="Italic"
							Foreground="{DynamicResource {x:Static themes:AssetResourceKeys.ContainerForegroundLowDisabledBrushKey}}" VerticalAlignment="Center" />
			</Border>
										
		</DataTemplate>
	</Setter.Value>
</Setter>

You could make an implicit Style in your Application.Resources that targets IntelliPromptCompletionList and updates that NoItemsTemplate to something else.

Hello,

Unfortunately we don't have anything to hide the completion list altogether when there are no items.

I understand.

Thank you for your support!
