## What it is
An Android library by Yalantis that implements a guillotine-styled drop-down menu animation for navigation layouts. It provides a builder API to customize the animation's duration, delay, interpolation, and lifecycle listeners.

## Use cases
- add a guillotine-style drop-down menu animation to an Android app
- animate a navigation menu that drops down like a guillotine
- customize menu open/close animation duration and interpolation
- add bounce effect to toolbar when menu closes
- implement a hamburger menu with a stylish transition

## When to choose
- you want a distinctive guillotine-style menu animation on Android
- you need a simple builder API to customize menu transition animations
- your app targets Android 4.0.3+ and uses Toolbar

## When to avoid
- you need a fully maintained library with active updates and a license file
- you want standard Material Design navigation patterns instead of custom animations
- you need menu animations for platforms other than Android

- function: animation, ui-components, mobile-framework
