Material Design has a comprehensive set of components, but no design framework can reasonably hope to cover all widgets.
Many of the UX StackExchange questions on Material Design on this site relate to a core question of what is and is not allowed under Material Design.
If there is a control that is not specified by Material Design, should I:
- Use it?
- Not use it?
- Check with someone/something and if so, what?
For example, iOS-style pagination, Windows-style file selector, or Tinder-style swipe interactions....but obviously there are many more widgets out there which are not covered.
Material Design guidelines seem silent on what to do here.
