The best way to eliminate the username of registration type in theme my login wp plugin?

I’ve tried disabling the username within the features.php by means of

 if(!is_admin()){
  remove_action( 'admin_color_scheme_picker', 'admin_color_scheme_picker' );
  add_action( 'personal_options', 'prefix_hide_personal_options' );
}
perform prefix_hide_personal_options() {
?>
<script kind="textual content/javascript">
  jQuery(doc).prepared(perform( $ ){
$("#registerform #user_login, #your-profile #user_login, #your-profile #nickname, #your-profile #display_name, #your-profile #url,  #your-profile #description").mother and father("div.form-group").cover();
  });
</script>
<?php
}

I’ve added this id identify #registerform #user_login to be hidden however nothing occurs within the registration type web page, nonetheless username is displaying up.

Any concept that might assist me level out the issue and what to do. I’m beginner in wp, do not have but stable understanding in plugins.
