## What it is
zTree is a jQuery-based tree view plugin for rendering hierarchical data in web pages. It supports JSON data, static and asynchronous loading, checkbox/radio selection, drag-and-drop editing, and theming with strong performance for large node counts.

## Use cases
- render a hierarchical tree from JSON data in a web page
- lazy-load tens of thousands of tree nodes asynchronously
- build a file or category browser with checkboxes and radio selection
- drag and drop tree nodes to reorganize hierarchy
- display multiple tree widgets on one page with custom skins

## When to avoid
- you are building a modern app with React, Vue, or another framework with native tree components
- you want to avoid jQuery as a dependency
- you need a maintained library with active development

- maturity: maintenance
- function: ui-components, frontend-framework
- domain: web-development, frontend
