Relation recordUrl open in new tab

If you want the recordUrl to open in a new tab you can do the following:

1. Add this code to your Controller

   public function relationExtendViewWidget($widget, $field, $model)
   {
   $partials_path = '$/author/plugin/partials/list/';
   $widget->addViewPath($partials_path);
   }

2. Copy modules/backend/widgets/lists/partials/_list_body_row.htm to your author/plugin/partials/list folder and modify to your taste.

3. Make sure to add an onClick() event on the 'a' tag

   <a <?= $this->getRecordOnClick($record) ?> href="<?= $url ?>" onClick="window.open(this.href)">
   <?= $this->getColumnValue($record, $column) ?>
   </a>
