You can toggle the sort order of classes displayed in the Class List of the Class Browser. By default, classes are displayed in hierarchical order but you can display them in alphabetical order, if required.
As no class hierarchy is visible when classes are displayed in sorted (alphabetical) order, you cannot see the structure of the schema.
To display classes in alphabetical order in the Class List of the Class Browser
Select the Sorted Order command from the View menu.
JADE then sorts all classes so that they are displayed in alphabetical order in the Class List window, and a check mark is displayed at the left of the command in the View menu to indicate that classes are currently displayed in alphabetical sort order.
For details about changing the display sort order so that it is effective for the current and all future work sessions until it is changed, see "Maintaining Browser Options", in Chapter 2. (As the default value is user‑specific, it applies only to your work sessions, and not those of other users.)
