Arguments

listdata

list or String data to view. Although designed for lists, listdata can be any data source that can be rendered into JSON with jsonlite. Alternately, listdata could be a String of valid JSON. This might be helpful when dealing with an API response.

enableClipboard

logical whether the user can copy objects and arrays clicking on the clipboard icon. Copy callbacks are supported. Default is TRUE.

displayObjectSize

logical whether or not objects and arrays are labeled with size. Default is TRUE.

onEdit, onAdd, onDelete, onSelect

htmlwidgets::JS or logical to control behavior on edit, add, delete, and select. If htmlwidgets::JS function is provided, then the function will be performed on each event. If logical then TRUE means that the event will be passed to Shiny and FALSE will disable the behavior. The default is TRUE.
