I've put together a quick demo of a menu idea for a mobile website or app. It only took me 20 minutes to build the entire prototype. Feel free to import and dissect.

The recently released Google Inbox app is a re-thinking of the email inbox experience that beautifully demonstrates Google's material design interactive animation language. This prototype focuses on the compose button's animation. Click the + to reveal a new state where a wave of buttons and labels float up, and the + becomes a pencil icon. It uses two states, with staggered animations.

A basic example of reproducing Instagram info bars behaviour. A list header floats over the list's items and remains visible at the edge of the screen until it is replaced by the next list header

Proto.io comes with UI libraries for iOS, Android Material Design, Windows and Apple WatchOS so that people can easily drag and drop those elements to bring their ideas to life. Simple interactions can also be applied, primarily screen-linking and basic navigation.

Designers can use their favorite design tools like Photoshop and Sketch to design the finest details of the user interface for their app. Single or multiple touch interactions can be applied on any UI element (layer) on each screen. Sophisticated animations can be created on-screen as well as screen transitions, using the powerful timeline animation features that Proto.io offers.

This is an expand/collapse menu example that can be created using container states.
