Explanation:
Administrators use Smart Lists to create custom drop-down lists that users access
from data
form cells. When clicking into cells whose members are associated with a Smart List (as a
member
property), users select items from drop-down lists instead of entering data. Users cannot type
in cells that contain Smart Lists. Smart Lists display in cells as down arrows that expand when
users click into the cells.
Perform these tasks to create and administer Smart Lists:
* Define Smart Lists
* Associate Smart Lists with members.
* Select dimensions for which Smart Lists are displayed.
