Hi,
I don't think it is possible to put a shortcode on that area.
That line is for the Template Builder's Text Area/Call out/Quotes element.
// $dynamic_text = apply_filters('the_content', $dynamic_text);
It will not affect the top banner. Anyway, you can find the code for the top banner on functions.php.
if(!function_exists('avia_banner'))
{
function avia_banner($position)
{
$extraClass = "";
$output = "";
$cookieHash = "";
$bannerText = avia_get_option('banner');
$cookieName = THEMENAME.'_avia_banner';
$bannerHash = md5($bannerText);
if($position) $extraClass = 'relative_pos';
if(!empty($_COOKIE[$cookieName])) $cookieHash = $_COOKIE[$cookieName];
$output .= "<div class='$extraClass container_wrap info_text_header' id='info_text_header' data-hash='$bannerHash' data-cookiename='$cookieName'><div class='container no_css_transition'>";
if(trim($bannerText) != "" && $bannerHash != $cookieHash)
{
$output .= "<div class='infotext'>$bannerText <a class='close_info_text rounded' href='#close'>".__('close','avia_framework')."</a></div>";
}
$output .= "</div></div>";
echo $output;
}
}
