## What it is
An Android dropdown menu library providing a complete filter solution for list screens. It uses adapters and generics so any model type can supply custom filter views, with checkable filter views and URL-building from selections.

## Use cases
- add a dropdown filter bar to an Android list screen
- build multi-tab filter menus like e-commerce category filters
- create single-select and multi-select dropdown filters
- generate query URLs from user filter selections
- customize dropdown panel views with adapters

## When to choose
- you need a ready-made dropdown filter menu on Android
- you want flexible custom filter panel views via adapters
- you prefer a lightweight Java library with a permissive license

## When to avoid
- your project is Kotlin-first and you want modern Jetpack Compose UI
- you need actively maintained components with recent updates
- you only need a simple Spinner without filter panels

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, form-handling
- domain: mobile-development, android-tools
- platform: -
- tags: dropdown-menu, filter, android-ui, java, android, mobile
