If you are creating a new field, the Enumeration Options list is empty. If you previously added values to the choice list of a field, those values are displayed in the list. Fields that have an assigned choice list are displayed in a list-box control or a combo-box control on associated forms.
If the Recalculate Choice List check box is selected, Rational ClearQuest updates the contents of the choice list as needed while the form containing the corresponding field is displayed. If this check box is not checked, Rational ClearQuest initializes the choice list when the form is first displayed and then does no further updates.
Use the Limit to List check box to restrict users from entering values that are not part of the defined choice list. If you select the Limit to List check box, you use either a list or a drop-down list (as opposed to a combo box) to display the field.
