Working with a Parent PageThe parent master page should contain all elements that are in common between it and its children. For example, let's say you have a book with ten chapters, and each chapter will use an identical layout with the exception of the chapter name as a running header. You can create one master page for the chapter content and then make ten master pages based on it. On each of the ten master pages you will only need to modify the running header, rather than having to build each master page from scratch. The difference between this relationship and simply duplicating the parent master is that making a change to the parent also affects the same elements on the child masters. Making Child MastersAfter building your parent master page, select the New Master command from the Pages palette's flyout menu. In the New Master dialog box, choose the parent master page from the Based On popup menu. When you click OK, the new master page will be a child master page (it'll be based on the parent master page; see Figure 32-1). Figure 32-1. A master page can be based on another master page.![]() You can also drag one master page icon on top of any other master page in the Pages palette. The page you drag becomes a parent master, the page you drop it on becomes a child master. The prefix on the master page icon indicates the relationship. Overriding Parent Items on a Child MasterWhile the idea for creating a parent master page is to have it format all child pages in one simple step, there will be times when you want to modify parent elements on a child master page. By default, parent items on child master pages are inaccessible for editing. However, you can make them accessible by Command-Shift/Ctrl-Shift-clicking on an item. Just keep in mind that once you do this, those items will no longer update if you change the same items on the parent master. We discuss this more in the next chapter. |
