select2_escape_markup

Hi, we have a select2 list of icons which return the relative URL e.g;

icons/red/cross.png : red cross
icons/green/square.png : green square

I’d like to show the image alongside the value, so I tried to use the select2_escape_markup filter but I can’t find any reference to the value of the option anywhere in any of the arguments (escaped_value, original_value, $select, settings, field, instance).

Can anyone help?

acf.addFilter(‘select2_escape_markup’, function(escaped_value, original_value, $select, settings, field, instance) {
if(field.data.name == ‘icon’) {
return original_value + ‘ ‘;
}
return escaped_value;
});
