Excerpt:
“Include line breaks (i.e. newlines, not HTML line breaks) between list items? The variables can additionally be augmented with filters. To use a filter, add a pipe character(|) followed by the name of the filter before the closing bracket in the variable, e.g. %[name|lower]% or %[number|zeropad]%.”
