Context maps
A context map is one of the top-level maps. When you designate a map as the context map for a topic, the software uses the designated context map to resolve any values or references defined at the map level.
You cannot add elements such as cross-references and conrefs without a context map.
Choose a context map
If a topic is in multiple maps, you can choose a map to designate as its context map when you edit the topic.
In some cases, you can change the context map set for a topic using the Details panel in Topic Editor. You can also set a context map using the Details panel if the topic does not have one.
No context map designation
Context maps are not automatically designated for all topics. Topics usually have a context map only when you are assigned to them, and topics can be assigned without a context map. However, you can always use the Details panel to designate a context map, and this does not require changing the assignments for the topic.
