You can allow or disallow spacing and indentation in topic titles:
[HelpOptions]
; TitleSpace = Yes (help title para can have space above/below),
; or No
TitleSpace=No
; TitleIndent = Yes (help title para can have left/right indents),
; or No
TitleIndent=No
By default, DITA2Go recognizes a hard return as the end of a topic title. If any topic titles continue past the first hard return, you can prevent this behavior:
[HelpOptions]
; HelpLineBreak = Yes (default, end topic title at hard return) or No
HelpLineBreak=No
