Replicating content across various pages is no easy task; copy-pasting can be cumbersome and time consuming. Use linked content features to manage multiple versions of content. You can place and link content within the same document or even across different documents. Linked content makes it easier to support emerging workflows, where for example, you design for vertical and horizontal layouts. Linked content also works well for traditional print and publishing workflows, where you synchronize boilerplate text on different pages or documents.
Linked content behaves similar to traditional links. See Use the Links panel for an overview. You can designate an object as parent, and then place it at other places as child objects. Whenever you update the parent object, the child objects are flagged and you can update them to synchronize with the parent.
