item line space

Suite and Optimus Suite 5

I am trying to add a empty label item between two block items to increase the line space between these two items. But it looks that the empty label has been ignored. how can I change the line space between two items.






	<item type="label" label="" labelHeight="30"/>

	<item type="label" label="Date">
		<item type="block" width="1200">
			<item type="calendar" name="createdDate" validate="NotEmpty" label="Created" position="label-top" />
			<item type="newcolumn"/>
			<item type="calendar" name="closedDate" label="Closed" position="label-top" />
			<item type="newcolumn"/>
			<item type="calendar" name="expiredDate" validate="NotEmpty" label="Expired" position="label-top" />
		</item>
	</item>

correct, empty label have 0px width
use offsetLeft/offsetTop for item
