How can I enter/display content in book icons? Not just in topics?

You’ll have to create a topic to associate with that book. Here’s one way to do that:

• Right click the book icon in the Table of Contents (TOC).
• Point to New in the right-click menu. Then, click Page in the sub-menu that displays.

This places that topic in the level under that book. Now you just need to associate that topic with that book (so that when you click on the book, this topic displays).

• Right-click the book icon again. This time select Properties in the right-click menu that displays. This displays the TOC Book Properties dialog.
• Select the checkbox preceding Book with Link on this dialog. Now, scroll through the Existing Topics list to locate the topic you want to associate with that book. Click that topic in the list. Then, click OK on the dialog.

To see if your topic is now associated with your book:

• Right-click the book icon. If options Edit Item and Preview topic display on the right-click menu, you have been successful in associating that topic with that book. By the way, once you have associated a topic with a book, you must right-click the book icon to view or edit that topic from the TOC pod. (Of course, you can always edit it directly using the Topic List or Project manager pods.)
