<div class="markdown level1 remarks"><p>The function takes three parameters: the data item, the current query text, and the display text after DisplayMemberPath processing. It returns the HTML to display for that item. Matches may be wrapped in any element; <code>wj-state-match</code> is the built-in highlight class. The HTML is rendered as-is and is not sanitized, so the function must escape any text it did not create; unescaped input allows cross-site scripting (XSS) attacks. The default value is null.</p>
