## What it is
Fancytree is a JavaScript tree view and tree grid plugin built on jQuery, supporting keyboard navigation, inline editing, filtering, checkboxes, drag-and-drop, and lazy loading. It is feature-complete and maintained for bugfixes only, with Wunderbaum suggested as its modernized successor.

## Use cases
- render hierarchical data as an interactive tree in the browser
- build a tree grid with columns and checkboxes
- implement drag-and-drop reordering of tree nodes
- lazy-load child nodes from a server on expand
- filter and search large tree structures
- allow inline renaming and editing of tree nodes

## When to choose
- you need a mature, feature-rich jQuery-based tree widget
- your stack already uses jQuery and legacy browser support matters
- you need treegrid, filtering, and drag-and-drop out of the box

## When to avoid
- you are starting a new modern project without jQuery
- you need actively developed new features or virtualized rendering for huge datasets
- you prefer a framework-native component for React, Vue, or Angular
