To select files, click the Select file button or drop the files directly on the component. If the upload mode is «useButtons», you must click the Upload button or a corresponding button for each file to initiate upload.
NOTE
This demo does not actually upload files. To upload files, assign the URL of a page providing server scenarios for saving uploaded files to the uploadUrl configuration property of the component.
