You can organize styles by grouping them into separate folders in the Character Styles, Paragraph Styles, Object Styles, Table Styles, and Cell Styles panels. You can even nest groups within groups. Styles do not need to be in a group; you can add them to a group or to the root level of the panel.
To create the group at the root level, deselect all styles.
To create a group within a group, select and open a group.
To include existing styles in the group, select the styles.
When you copy a style to a different group, the styles are not linked. Even though they have the same name, editing one style does not change the attributes of the other style.
