The <topichead> element provides a title-only entry in a navigation map, which should appear as a heading when the map is rendered as a table of contents. In print contexts it should also appear as a heading in the rendered content.

Note that in the following example, the first <topichead> element uses a <navtitle> element to provide the title, while the second <topichead> element uses a navtitle attribute. This is only to illustrate that both uses are valid; in general, the element is preferred over the attribute.
<map>
<topichead>
<topicmeta><navtitle>Computers</navtitle></topicmeta>
<topicref href="eniac.dita"/>
<topicref href="system360.dita"/>
<topicref href="pdp8.dita"/>
</topichead>
<topichead navtitle="Books">
<topicref href="hardback.dita"/>
<topicref href="paperback.dita"/>
</topichead>
</map>
| Name | Description | Data Type | Default Value | Required? |
|---|---|---|---|---|
| navtitle | Specifies the title of the topic as it will appear in the navigation or tables of contents that are generated from the map. Beginning with DITA 1.2, the preferred way to specify the navigation title in a map is with the navtitle element, available inside the topicmeta element. | 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 attribute group (collection-type, processing-role, type, scope, locktitle, format, linking, toc, print, search, chunk) | A set of related attributes. See topicref-atts, topicref-atts-no-toc, and topicref-atts-without-format attribute groups. | |||
| univ-atts attribute group (includes select-atts, id-atts, and localization-atts groups) | A set of related attributes, described in univ-atts attribute group | |||
| global-atts attribute group (xtrf, xtrc) | A set of related attributes, described in global-atts attribute group | |||
| class, outputclass | Common attributes described in Other common DITA attributes |
