The dropzone widget creates an area into which the user can drag files and other objects. It also supports pasting via the clipboard, although browser support is currently limited.
It sends a WidgetMessage: tm-import-tiddlers carrying a JSON representation of the tiddlers to be imported up through its parents. This message usually trapped by the NavigatorWidget which adds the tiddlers to the store and updates the story to display them.

The dropzone widget displays any contained content within the dropzone.
The dropzone widget creates an HTML
<div class="tc-dropzone"> to contain its content. During a drag operation the class
tc-dragover is added. CSS is used to provide user feedback. For custom styling of this state where a drag is in progress, specify a custom class name with the
class attribute and use CSS with the selector
