This is the code that was working on laravel 5.2
$menus = CmsMenuItem::groupBy('menu_id')->get();
but now it throws error
SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'convertifier_cms.cms_menu_items.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by (SQL: select * from 'cms_menu_items' group by 'menu_id')
I have also tried
`strict => false`
in database.php but no effect
