I'd like to tidy up an unwieldy node edit form using collapsible
I can do this by implementing a form_alter hook but will this affect Drupal/other modules' ability to process/validate the fields? Obviously it will change the
#parents of several elements, and I'm unclear whether this change will also affect
Is it safe to do this, or is there another way to achieve the same?
$form['group1'] = [ '#type' => 'fieldset', '#title' => 'My Grouped Fields', '#collapsible' => TRUE, '#collapsed' => TRUE, 'children' => [ 'body' => $form['body'], 'field_smallprint' => $form['field_smallprint'] ], ]; unset($form['body'], $form['field_smallprint']);
It seems to me that this is probably safe unless
TRUE, but I don't want to implement something that might lose data, hence the question here.
