به‌وسیله‌ی order میتوان ترتیب قرارگیری آیتمهای Grid را مشخص کرد. فرض کنید یک ردیف سه ستون داریم و می‌خواهیم زمانیکه این آیتمها در مروگر نمایش داده می‌شوند، ترتیب قرارگیری آنها متناسب با نیاز ما باشد که با استفاده از دستور order این کار صورت می‌پذیرد. 

نکته: این کار برای بحث seo مورد استفاده قرار میگیرد.
