I have a typical content type, with a field, let’s say field_name.
I can output each field using the field.html.twig file. In the file, to output each item, there is a line
<div{{ item.attributes }}>{{ item.content }}</div>
So how can I set item.attributes, to output, say, the machine name of the field, so that my output is:
<div class="field_name">My Name</div>
I suspect it has to do with using the:
function theme_preprocess_field(&$variables) {
$item['content']['#item_attributes']['class'][] = $variables['field_name'];
Is this correct? Where do I go from here? How can I make this work?
Thanks!!
