File upload
A control that lets users add files from their device.
A file upload control lets the user pick a file (or several) from their device and attach it to a form. It usually appears as a button labeled "Choose file" or as a large drop zone for drag-and-drop.
Show a preview of the selected file once chosen, with the file name, size, and a remove button. For images, a thumbnail makes it obvious the right file was picked.
