The <topicref> element identifies a topic (such as a concept, task, or reference) or other resource. A <topicref> can contain other<topicref> elements, allowing you to express navigation or table-of-contents hierarchies, as well as implying relationships between the containing <topicref> and its children. You can set the collection-type of a container <topicref> to determine how its children are related to each other. You can also express relationships among <topicref>s using group and table structures (using <topicgroup> and <reltable>). Relationships end up expressed as links in the output (with each participant in a relationship having links to the other participants by default).
You can fine tune the output from your map by setting different attributes on topicrefs: for example, the linking attribute controls how its relationships to other topicrefs are expressed as links, and the toc attribute controls whether the topicref shows up in TOC or navigation output.

Name | Description | Data Type | Default Value | Required? |
---|---|---|---|---|
navtitle | Specifies the title of the topic as it will appear in navigation or tables of contents generated from the map. | CDATA | #IMPLIED | No |
href | A pointer to the resource represented by the <topicref>. References to DITA content cannot be below the topic level: that is, you cannot reference individual elements inside a topic. References to content other than DITA topics should use the format attribute to identify the kind of resource being referenced. | CDATA | #IMPLIED | No |
query | This attribute is deprecated. It may be removed in the future. | CDATA | #IMPLIED | No |
copy-to | Use the copy-to attribute on the <topicref>
element to provide a different file name for a particular instance of the
topic in the map (for example, to separate out the different versions of the
topic, rather than combining them on output). The links and navigation associated
with that instance will point to a copy of the topic with the file name you
specified. Use the <linktext> and <shortdesc> in the <topicref>'s <topicmeta> to provide a unique name and short description for the new copy. |
CDATA | #IMPLIED | No |
%topicref-atts; (collection-type, type, scope, locktitle, format, linking, toc, print, search, chunk) | A set of related attributes. See %topicref-atts; and %topicref-atts-no-toc;. | parameter entity | PE not applicable | Not applicable |
