Tree view

Nested tree display with single-select / checkbox (with cascading), expand / collapse, and custom icons.

Basic usage

nodes is a tree (each node may have children). selectedKey + update:selectedKey controls the single-select highlight; defaultExpandedKeys sets initially expanded node keys. disabled nodes don’t respond to clicks.

Checkbox with cascading

checkable adds a checkbox to each node, paired with v-model (Vue) / value + onChange (React) bound to string[]. cascade=true (default) makes parent / child checks affect each other — checking a parent checks all descendants, and checking all descendants checks the parent; half-checked state becomes indeterminate automatically.

With cascade=false, each node is independent, useful for industry / tag multi-select cases.

Sizes

size controls node row height and font size — sm compact (common in sidebar file trees) / md default / lg for touch-friendly use.

Hide connector lines

showLine={false} hides the dashed parent-child connectors — cleaner look, often paired with custom icons.
