Categories are used to organize information types into groups. Examples of categories include Job Description, Skill Level, and Topic Type. To define information types, you first create the categories.
From the File menu, select Project Settings.
Click the Information Types tab.
In Category, enter the name to assign to the category.
Classify the category as follows:
Inclusive: Allows users to select any combination of information types that belong to a category.
Exclusive: Restricts users so they can only select one information type from a category.
Hidden: If you are assigning topics to information types that will only be used for context-sensitive Help, select this option. Users do not see these topics in the table of contents nor can they customize information types to filter them in any way. These are used by your developer to control access to the topic.
Click Add. The new category is added.
In Information Type, enter the first information type to include in the category.
Click Add. The information type is added to the category and it appears at a list on the right.
Repeat steps 7 and 8 until you finish adding all information types to the category.
