Grass path

When i trying to learn new snapshot suddenly i discovered that i can make a grass path but thing is when you are in creative mode you can click your mouse roll and you can get the item in your inventory(am i wrong?)but after a while i saw a video on youtube that they said that you cant get this item in your inventory even if you are in creative mode like block so i had a gif that will show what i said
