Yep, add the widget ‘Dataview’ on the page. Make sure it has as Data-resource: an entity of type System.FileDocument. Then drag the widget ‘File Manager’ into the Dataview.
Hey Vladylav,
First you have to make a generalization of the entity(where you want to store file) with the system.file.
And then on the page where you want to upload file,
Add a data view and then add then add a file uploader widget. That way you'll be able to upload the file successfully.
Hope it helps!
