Ability to select and preview multiple files
Includes file browse and optional remove and upload buttons.

Ability to preview multiple files of different types (both images and text)
Set your upload action/route (defaults to form submit). Customize the Upload and Remove buttons.
Internationalization enabled for easy translation to various languages

NOTE: This extension is a sub repo split of yii2-widgets. The split has been done since 08-Nov-2014 to allow developers to install this specific widget in isolation if needed. One can also use the extension the previous way with the whole suite of yii2-widgets.
