Moving objects forward or backward on a layout
When objects overlap on a layout, one object is on top of the other. You can change this stacking order to create different effects. As you create objects, they stack one on top of the last, even if they aren't overlapping, so that the last object created is always on top.
Original stacking order
Object moves to the front of the stacking order for the Bring to Front command
Object moves to the back of the stacking order for the Send to Back command
Object moves forward in the stacking order for the Bring Forward command
Object moves backward in the stacking order for the Send Backward command
To change the order in which objects are stacked:
In Layout mode, select the object or objects to move in the stack.
For more information, see Selecting objects.
Click Inspector Inspector button in the layout bar, then click Position.
Note  Objects located in tab controls, slide controls, popovers, or portals maintain a stacking order within the tab control, slide control, or portal. For example, if you select an object on a tab control and click Send to back Send to Back button, the object moves behind all the other objects on the tab control, not behind all objects on the layout.
