[meta] Layout builder for orders

abx that would make sense. The default order template does never render the entire order, only its individual fields.

Could you try changing commerce/modules/order/templates/commerce-order--admin.html.twig (assuming you are working on the admin view mode) and place {{ order }} somewhere in that template? That should render the order with layout builder enabled.

I suppose we need to find a way to make the fields layout use that template, but have layout builder use the commerce-order.html.twig template instead.

To give you the best control, I think you should change the twig template to only contain {{ order }}. The reason you see double fields is because of the item being rendered as part of {{order}} but also individually as {{order.field_name}}.

I'll have a look at the fields you're missing later this week. It could be a known issue in core. Could you try disabling layout builder, then place the missing fields into the enabled section and then turn layout builder back on. Do they show then?

Thanks abx, for taking the time to look around and pinpoint the missing items.

I've played around and got the shipping information to show (with 2 profiles though... ?) by using the following hook in commerce_shipping:

/**
 * Implements hook_entity_extra_field_info().
 */
function commerce_shipping_entity_extra_field_info() {
  $return = [];
  foreach (OrderType::loadMultiple() as $order_type) {
    $return['commerce_order'][$order_type->id()]['display']['shipping_information'] = [
      'label' => t('Shipping information'),
      'weight' => 100,
      'visible' => TRUE,
    ];
  }
  return $return;
}

For commerce activity, not tested, but simply looking at commerce_log_preprocess_commerce_order I'd assume the exact same hook should work:

// Add this to the top.
use Drupal\commerce_order\Entity\OrderType;


/**
 * Implements hook_entity_extra_field_info().
 */
function commerce_log_entity_extra_field_info() {
  $return = [];
  foreach (OrderType::loadMultiple() as $order_type) {
    $return['commerce_order'][$order_type->id()]['display']['activity'] = [
      'label' => t('Order activity'),
      'weight' => 100,
      'visible' => TRUE,
    ];
  }
  return $return;
}

Though I've also seen how fields from linked entities can be shown in the layout builder. (eg. product variation field when editing a product.). I just have no idea about the complexity of that.
Updated the issue summary with both options.
