Use this drop down list to change which types of item class are displayed. You can choose to view user or system defined classes, and choose to display the different types of class (for example, list of values or alternative sort).
You can review the list of values assigned to an item class, in each item class folder. When you open a list of values folder Discoverer displays each unique occurrence of data values as a set. This display clearly shows which items use a particular item class.
