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.

Have a look at this stunning Parallax effect created exclusively with Proto.io. Feel free to import this fully editable project into your own account for use in your prototypes.

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.

Tap/Hold the black circle to see the 2 state animation of the Keezy sound looping app. A circle of circular buttons spins out onto the expanded black circle that becomes the screen background. Once you're on this 2nd state, tap anywhere to return to the initial state. I recorded a webinar showing how to create this interactive animation: http://docs.proto.io/videos/re-creating-bespoke-interactive-animations-with-proto-io-2/ You can also find the assets here used for the prototype. Enjoy!

This simple prototype demonstrates how have a container expand and collapse while moving adjacent content in sync.

3 prototypes showing different uses of the form components for iOS 1) Activate / de-activate button when checking / un-checking Terms of Service 2) Capture text input to change property 3) Change number of tickets - limit 8 See how they were created step-by-step in the Using Forms webinar video: https://vimeo.com/118919393 This version on Vimeo includes time-codes so you can jump to particular sub-sections (repeated below as a preview): > Range of iOS form input controls 2:02 > Labels 2:17 > Text fields 2:32 > Setting placeholder text 3:04 > 5 Input Types that display the appropriate iOS keyboard (Text, Numeric, Email, Password, Telephone) 3:30 > Using the Telephone keyboard for credit card number input (large # keys) 4:08 > Need to view prototype on device in order to see the range of keyboards 5:59 > Multi-line text area input field 6:24 > Search Bar 6:40 > Checkbox control customization 7:22 > On/Off Switch control customization 7:52 > Slider control customization 9:27 > Increasing size of slider handle 9:47 > Picker Wheel Customization 10:00 > Prototype example: Activate button when checking terms of service 10:42 > Create a button with two states (using convert to container) 12:55 > Adding interactions to a checkbox control (on change activation/deactivation) 14:45 > Definition of variable and range of uses 17:04 > Using variables with text field interactions 18:25 > Prototype Example: Using a variable to capture text input and show it in a different text box using change property. 23:27 > Prototype: Use variables to increment and decrement counter showing number of tickets being purchased. 28:40 > Searching full range of icons built into Proto.io 29:10 > Using a variable to limit the range of tickets (0 to 8) 32:46 > Copying and pasting interactions with Variables 40:08

If you need to get the Y position of a vertically scrolling container, create a text box. Then on the container scroll trigger, set a variable that evaluates the numerical callback value from the event (Y position). Then add a callback that changes the text property of the text box by reading from the variable.
