The fields for some Keyword Types may contain a drop-down list. Select any value from this list as criteria for document retrieval. If the Keyword Type field contains any characters, values in the drop-down list are filtered by these characters. Your system administrator determines if a drop-down list appears for a Keyword Type, and what values will be in the list.
If two or more consecutive Keyword Types contain drop-down lists and are ordered in such a way as to show a hierarchical parent/child relationship, the Keyword Types may be part of a Cascading Data Set.
For information about Cascading Data Sets, see Cascading Data Sets.
