## What it is
A lightweight, flexible tree view component for React that supports nested TreeView nodes and customizable styling via CSS. It offers controlled and uncontrolled collapse state through simple props.

## Use cases
- render a collapsible tree view in react
- display hierarchical data with expand/collapse nodes
- customize tree node styling with css classes
- build a file explorer style tree in react
- nested tree component with uncontrolled collapsed state

## When to choose
- you need a minimal, dependency-light tree component for React
- you want full control over styling via plain CSS
- you prefer a simple API with controlled or uncontrolled collapse state

## When to avoid
- you need virtualized rendering for very large trees
- you require built-in features like drag-and-drop, checkboxes, or search
- you need a component with an active maintenance guarantee or explicit license file
