I can just give you a vague answer, but there are methods on the widget, which get called within the .display() call in your template. If you supply values to the call to .display(), you can access those in that functions and use it to display dynamic dropdown options.
Here's an example: https://github.com/moschlar/SAUCE/blob/develop/sauce/widgets/submission.py#L35 self.value holds exactly what you pass in to the call to .display(). Am Freitag, 2.
