I used the Sketch "Delicious" free UI Kit for a food recipes app. It includes 11 pixel-perfect screens. I just added Proto.io interactions and created a great prototype! This Delicious UI Kit was designed by Robert Anitei Sketch source: https://www.sketchappsources.com/free-source/1765-delicious-ui-kit-sketch-freebie-resource.html

Since Halloween is coming up I created this project using Proto.io's free Halloween icon pack. I simple onboarding process using scrollable containers with on swipe interactions.

A website template with multilevel dropdown menus and scrolling area.
