The Attribute Description for variable attributes can be used to determine the control that the HPCA Administrator CSDB Editor displays for entering or editing that attribute in the Editing Instance dialog box. Normally, variable attributes are entered or edited as free text in a text box. You can change this to a check box, a set of check boxes, or a drop-down list.
To enable this feature, select the Use Edit Masks When Editing Instances option on the Instance Options tab of the Options dialog box. For details, see "Setting Preferences: Options Dialog Box".
