Hi,

Please try this PHP snippet:

add_filter( 
 'hivepress/v1/models/listing/attributes', 
 function ($attributes){
  if(isset($attributes['tags'])){
   $attributes['tags']['edit_field']['max_values'] = 20;
  }
  
  return $attributes;
 },
 1000
);

add_filter( 
 'hivepress/v1/models/listing',
 function ($model){
  if(isset($model['fields']['tags'])){
   $model['fields']['tags']['max_values'] = 20;
  }
  
  return $model;
 },
 1000
);

add_filter( 
 'hivepress/v1/forms/listing_update/errors', 
 function ($errors, $form){
  if(count((array)$form->get_value('tags')) < 1){
   $errors[] = 'Please set at least one tag';
  }
  
  return $errors;
 },
 1000,
 2
);

Please note that you may require additional customizations in the future.
