Toloka documentation

field.file

This component can be used for uploading files. It's displayed in the interface as an upload button.

You can list in the accept property the file types that will be suggested to a Toloker when uploading. By default, only one file can be uploaded, but you can allow multiple files in the multiple property.

If a Toloker logs in from a mobile device, it's more convenient to use field.media-file — it's adapted for mobile devices and makes it easier to upload photos and videos.

In the task review mode, the uploaded images will appear automatically. You can view, rotate, and switch among the images.
