A topic is the smallest piece of content that users can bookmark, or add to a Personal book.
By learning how to use the chunk attribute for DITA topics, content authors can:
- Combine multiple topics into a single topic (
chunk="to-content" outputclass="ft-merge"). - Combine multiple topics into a single topic according to metadata (
chunk="to-content").
See the Chunking topic of the DITA specification for more information.
