Gmail has functionality where dragging an attachment to, say, the Windows desktop, automatically downloads the attachment and saves it on the Desktop. Does anyone know how to replicate this drag and drop behavior on with an R Shiny Upload control? Currently I can download a GMail attachment and then drag it to a Shiny Upload control, but I can't drag the attachment straight to the Shiny Form with the Upload control from GMail.
Thank you,
