To apply a drop shadow, select the item and check Apply Drop Shadow in the Drop Shadow tab of the Measurements palette or the Modify dialog box (Item menu). You can apply drop shadows to the shape of an item — box, line, text path, table — provided that the item has a background color applied to it. You can apply a drop shadow to text when the box background has an opacity of less than 100%. You can apply a drop shadow to the contours of a picture when a clipping path or alpha mask is selected and the box background is None. You can apply a drop shadow to a group with the drop shadow reflecting the collective shape of all of the items in the group.
