This tutorial demonstrates how to add a File URL selector in Feather widget's designer view. This selector lists files that you have inside Sitefinity's web application folder and allows you to select existing file. As a result, you get the selected file's URL.
The values of the attributes are scope properties that you must added in your widgets controller.
You use the sf-model attribute to set or retrieve selected file URL. You use the sf-extension attribute to restrict allowed files depending on their extension. The sf-extension attribute is a required attribute.
