To change the placement order of subtypes

By default, when types are added to a type tree, they are placed in alphabetical or ascending order. In addition to ascending order, you can change the default placement order of new types to be descending, first in the list, or last in the list. To change the placement order of types for a type tree, modify the properties of the root type.
  1. Open the properties of the root type.
  2. Go to the Order Subtypes property and make a selection from the drop-down list: Ascending, Descending, Add First, or Add Last.
  3. Save changes.
