## What it is
An Objective-C iOS library providing a two-level collapsible classification menu built with UICollectionView, plus a multi-select sidebar menu variant. It supports persisting the user's filter selections across app launches using NSCoding.

## Use cases
- build a collapsible two-level filter menu in an iOS app
- add a product review filter like Taobao's collapsible criteria
- create a search category filter menu like Maimai's app
- persist user filter selections between app launches
- implement a multi-select sidebar category menu on iOS

## When to choose
- you need a two-level collapsible or sidebar filter menu in an Objective-C or Swift iOS project
- you want user filter selections remembered across sessions out of the box

## When to avoid
- you need a maintained library with active support or a clear license
- you are building for Android or cross-platform frameworks
- you need a menu style other than collapsible two-level or sidebar filters
