The following example is for adding a hook callback.

// define the ninja_forms_display_required_items_class callback 
function filter_ninja_forms_display_required_items_class( $ninja_forms_required_items, $form_id ) { 
    // make filter magic happen here... 
    return $ninja_forms_required_items; 
}; 
         
// add the filter 
add_filter( 'ninja_forms_display_required_items_class', 'filter_ninja_forms_display_required_items_class', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'ninja_forms_display_required_items_class', 'filter_ninja_forms_display_required_items_class', 10, 2 );
