```ruby
class RegistryItemDecorator < MiqDecorator
  def self.fonticon
    nil
  end

  def fileicon
    "100/#{image_name.downcase}.png"
  end
end
```

Use fonticons instead of fileicons in the RegistryItemDecorator
user
```ruby
class RegistryItemDecorator < MiqDecorator
  def fonticon
    image_name == 'registry_string_items' ? 'ff ff-file-txt-o' : 'ff ff-file-bin-o'
  end
end
```
