Additional options control how drop shadows interact with items, including handling opacity and text runaround. As with the other controls, these options are located in the Drop Shadow tab of the Modify dialog box (Item menu) or the Measurements palette.

• Use Inherit Item’s Opacity to have the drop shadow reflect different opacities in the item, such as differences in the box background and frame.
• Use Item Knocks Out Drop Shadow to prevent a shadow from displaying through semi-opaque areas of an item — to keep a shadow from peeping through its box, for example.
• Use Runaround Drop Shadow to include a drop shadow with the text wrap contour specified in the Runaround tab (Item > Modify).
• Use Inherit Item’s Opacity and Item Knocks Out Drop Shadow combined to achieve different results based on the combination of these settings, as shown here.

At far left, both Inherit Item’s Opacity and Item Knocks Out Drop Shadow are unchecked. Second from left, only Inherit Item’s Opacity is checked. At far right, both options are checked.
