Per-assignment behaviour
When you assign a keyword to a document type, you also control how it behaves on that type’s indexing form. The same keyword type can behave differently on different document types — required on one, hidden on another — because behaviour is set on the assignment, not on the keyword type itself. You set these on each keyword in the assignment editor under Admin settings → Keywords → Keyword assignments. To change one setting across many keywords at once, use bulk edit.
The behaviour flags
Read-only and hidden are different: a read-only keyword is visible but locked, a hidden keyword is not shown at all. Combine default value with read-only to stamp a fixed value users can see but not change.
Conditional keyword rules
Beyond per-keyword flags, you can define conditional rules that change keyword behaviour based on other values — for example, show a keyword only when another keyword has a particular value, or set a default conditionally. Manage these under Admin settings → Keywords → Keyword behavior. Conditional rules are scoped per document type and are evaluated live on the indexing form as users enter values. They’re the tool to reach for when a static required or hidden flag isn’t enough and the behaviour needs to depend on context.
