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.
This is a prototype that demonstrates you some of the capabilities of Proto.io. You are welcome to import this project and use these interactions in your prototypes.
In this prototype you will see drag animations in all directions.
