The highlightPreTag parameter defines the HTML tag inserted before the matching text in highlighted attributes. It works in combination with highlightPostTag, which marks the end of the highlighted portion.

​
Usage

  • Set an empty string ("") to fallback to the default tag.
  • To turn off highlighting, remove the searchable attribute with the attributesToHighlight parameter.

​
Examples
