Events #

Name Type Description sp-dropzone-dragleave Event Announces when dragged files have been moved out of the UI without having been dropped. sp-dropzone-dragover Event Announces when files have been dragged over the UI, but not yet dropped. sp-dropzone-drop Event Announces when dragged files have been dropped on the UI. sp-dropzone-should-accept Event A cancellable event that confirms whether or not a file dropped on the UI should be accepted.

Description #

A <sp-dropzone> is an area on the screen into which an object can be dragged and dropped to accomplish a task. For example, a DropZone might be used in an upload workflow to enable the user to drop a file from their operating system into the DropZone, which is a more efficient and intuitive action, rather than utilize the standard "Choose File" dialog.

DropZones should be used with an IllustratedMessage component as a child if the drop zone is empty, otherwise the existing content should be passed as a child.

Accessibility #

When actions, e.g. copy/paste, can be enacted directly on the <sp-dropzone> element itself, be sure to supply a tabindex so that keyboard users can find this interaction in the tab order. For screen readers, be sure to announce what the actions are, how to complete them, and when they are completed by supplying the appropriate role and aria-label attributes.
