Understanding Options in Style Designer
The Options tab allows you to define the behavior of the selected item in Style Designer. For example, you can set the options for a paragraph style to create an expand/collapse section or to split the content and start a new output file. The available options depend on the selected item, such as a paragraph style or a marker style, and the active target, such as WebWorks Help or Eclipse Help.
The options you specify for a parent style are not inherited by child styles.
