Hello,

The cloneable is set in the group level so I think you will need to use a for loop to get the group item and check the subfield value inside the loop. For example:

function list_sanitize($values){
    //list - group clone
    foreach ( $values as $key => $value ) {
        $jtitle = isset( $value['jtitle'] ) ? $value['jtitle'] :[]; //title
        if( !empty($jtit) ){
            $values[$key]['jtitle'] = sanitize_text_field($jtitle);
        }
    }
    
    return $values;
}

Let me know how it goes.

Thank Mr. Peter,
But no response for the code. I have checked as $values[$key]['jtitle'] = 'Hello world';

Hello Peter,
I believe the issue is still with the values from the [group clone] $values. I simply used the database data that was unserialized and serialized using your technique, and everything went smoothly. I believe the issue is values being passed to the sanitize function. Note: It only applies to clone values.
