16.2.2 Specifying topic levels in ditamaps

To specify map levels for topics, assign a level number to each FrameMaker format that you map to a <title> element at the topic level in [DITAParaTags]; see §15.4.3 Mapping paragraph formats to DITA block elements. For example:

[DITAMapLevels]

; Frame para format = level of topics it starts in ditamap, default 1.

Heading1 = 1

Heading2 = 2

Each instance of a paragraph format assigned a level number generates a <topicref> that nests the lower <topicref> elements. For paragraph formats that are not listed here, but that are mapped to <title> elements at the topic level in [DITAParaTags], Mif2Go uses any level assignments you have provided for those formats in [HelpContentsLevels]. See §7.4.4 Setting contents levels for HTML-based Help.

If you direct Mif2Go to nest topics (see §15.8.4 Nesting DITA topics in unsplit files), Mif2Go adjusts map levels as follows:

• If a topic is nested in a glossary topic (which is invalid), the map level of the nested topic is decreased to make it a sibling of the glossary topic.

• If a topic is set to a level more than one deeper than the previous topic, its level is decreased so that no levels are skipped.

Any adjustments to map levels also affect the chapter ditamap.
