SID-02343: New line in varCHILDREN

How can I render %CHILDREN% at a new line? VarCHILDREN says: "Supports same format strings as SEARCH. See FormattedSearch for usage, variables & examples", but $n doesn't seem to work (%CHILDREN{format="$topic$n()"}%), nor separator="$n" seems to work.

Discussion and Answer

Oh, I guess it does work, and you just don't see it after HTML rendering. The format parameter works as a replacement in the TWiki markup, like you see it in "Raw edit" mode. A single line break doesn't end a paragraph in wiki markup!

To see a line break in your page, you have several options. Note that all cases I add the newline to the format parameter, to make sure that it is also added after the last child:

• Use either two consecutive line breaks to separate like paragraphs, or the %BR% markup for a new line without paragraph spacing:
  • format="$topic$n$n" separator="" or format="$topic%BR%" separator=""
• Or use a format where a single line break in the wiki source matters.
  • A list: format="   * $topic$n" separator=""
  • A table: format="| $topic |$n" separator=""

Thanks Harald. format="$topic$n$n" separator="" doesn't work in my environment, but format="$topic%BR%" separator="" works fine.
