## What it is
Cascade is a Kotlin library for Android that builds nested popup menus with smooth height animations. It serves as a drop-in replacement for both PopupMenu (Views) and DropdownMenu (Jetpack Compose).

## Use cases
- show nested dropdown menus in an Android app
- replace DropdownMenu with animated cascading submenus in Compose
- add smooth height animations to popup menus
- build hierarchical menus for Android Views
- display cascading context menus on Android

## When to choose
- you need nested/cascading popup menus on Android
- you want a drop-in replacement for PopupMenu or DropdownMenu
- your app uses Jetpack Compose or the Android View system and needs animated menus

## When to avoid
- you need menus on platforms other than Android
- you only need simple flat menus without nesting or animations
- you're not using Kotlin or Android's View/Compose UI toolkits

## Facets
- artifact type: library
- maturity: stable
- function: ui-components, animation
- domain: mobile-development, android-tools, frontend
- platform: jvm
- tags: jetpack-compose, popup-menu, dropdown-menu, nested-menus, android
