Single post in Fields are now sellable

That has been there a while, it is for Mobile users who can not drag and drop due to screen size or whatever. But click and drag still works fine on my laptop.

Post what Browser you use and include the screenshot for posterity, although I don't see anything in it that would help, maybe he would.
