Summary
Most InDesign pages are made up of several objects. Each object occupies a separate level in a page's stacking order. The first object you place on a page occupies the bottom layer, and each new object you create or place occupies a new layer that's on top of all other layers. You can change a page's stacking order by moving individual items forward or backward in the stacking order. InDesign also provides several options for working with several objects at once. When multiple items are selected, you can combine them into a group that behaves like a single item. You can also place an object within a frame to create a nested object, and you can insert objects within a text thread to create inline frames that flow with the surrounding text.
