The FIELD element specifies a data value to be displayed in a CLUSTER, a value to be retrieved from the user via an input control in a CLUSTER, or a list of data values to be displayed in a LIST column. FIELD elements can also be aggregated within CONTAINER elements so that they fill a single cell of a CLUSTER or LIST element.
Please note that, when the FIELD element is used to display a code table hierarchy either on an edit or ready-only page, the following should apply:
- For an edit page, only one FIELD element is needed to display a code table hierarchy with a domain definition inherited from CODETABLE_CODE that has the code table name set to the lowest level code table in a hierarchy. The CDEJ infrastructure automatically determines its code table hierarchy and then displays however many dropdowns it has, i.e. if it is a three level hierarchy, then the three levels are displayed.
- For a read-only page, however only the lowest level code table value is displayed on the screen by the same way using a single FIELD element as the edit page. And the CDEJ infrastructure does not support on displaying its full hierarchy.
