Deactivate Fields

Hi,

How can I deactivate the fields I don’t need?

I saw you answered this question in another post, but can you please be more specific? Where exactly do I place the following filter? I mean, in what file and where?

add_filter(‘job_bm_filters_job_meta_options’, ‘job_bm_filters_job_meta_options_extra’ );
function job_bm_filters_job_meta_options_extra($options){
// unset/remove any meta fileds
unset($options[‘<i class=”fa fa-university”></i> Company Info’][‘job_bm_company_name’]);
return $options;
}
