+
+\item{label}{Display label for the control, or \code{NULL} for no label.}

+\item{multiple}{Whether the user should be allowed to select and upload
+multiple files at once. \strong{Does not work on older browsers, including
+Internet Explorer 9 and earlier.}}
+
+\item{accept}{A character vector of "unique file type specifiers" which gives
+the browser a hint as to the type of file the server expects. Many browsers
+use this prevent the user from selecting an invalid file.

+A unique file type specifier can be:
+\itemize{
+\item A case insensitive extension like \code{.csv} or \code{.rds}.
+\item A valid MIME type, like \code{text/plain} or \code{application/pdf}
+\item One of \verb{audio/*}, \verb{video/*}, or \verb{image/*} meaning any audio, video,
+or image type, respectively.
+}}

+\item{width}{The width of the input, e.g. \code{'400px'}, or \code{'100\%'};

+This attribute facilitates user access to a device's media capture
+mechanism, such as a camera, or microphone, from within a file upload
+control.
+
+A value of \code{user} indicates that the user-facing camera and/or microphone
+should be used. A value of \code{environment} specifies that the outward-facing
+camera and/or microphone should be used.
+
+By default on most phones, this will accept still photos or video. For
+still photos only, also use \code{accept="image/*"}. For video only, use
+\code{accept="video/*"}.}
