## What it is
An Android library providing a two-level linked (linkage) RecyclerView, like the category-to-item list used in food delivery apps such as Ele.me. It is built on MVP architecture and can be initialized with a single line of code using default grouped item data.

## Use cases
- add an eleme-style two-level linked list to an android app
- build a category sidebar that scrolls a grouped item list
- implement a food delivery menu ui in android
- sync scrolling between a primary list and secondary recyclerview
- learn mvp architecture best practices for android libraries

## When to choose
- you need a ready-made two-level linkage list on android with minimal setup
- you want a customizable grouped list via a simple Config class
- you want a reference for MVP-based third-party android library design

## When to avoid
- you need a non-android or Jetpack Compose implementation
- you need complex multi-level nesting beyond two levels
- you require a maintained library with an explicit license or active releases
