Usage

import Nestable from 'react-nestable';

// this usually goes once
// to the entry point of the whole app
// (e.g. src/index.js)
import 'react-nestable/dist/styles/index.css';

// every item must have a unique `id`
// in order to distinguish elements
const items = [
  { id: 0, text: 'Andy' },
  {
    id: 1, text: 'Harry',
    children: [
      { id: 2, text: 'David' }
    ]
  },
  { id: 3, text: 'Lisa' }
];

const renderItem = ({ item }) => item.text;

const Example = () => (
  <Nestable
    items={items}
    renderItem={renderItem}
  />
);

Options

Property	Type	Default	Description
childrenProp	string	"children"	Name of a property for children.
className	string	undefined	Extra class name which can be passed to a root element.
collapsed	boolean	false	Makes groups collapsed by default.
confirmChange	function	() => true	Callback which has a single parameter with keys: dragItem - item which is being dragged, destinationParent - item where dragItem is about to land (or null if moving to root). Let function return false if this movement should not happen.
disableCollapse	boolean	false	Disable toggling a collapsed state of items with children. If you need to set a specific initial state, then it is still possible to do so with the public method collapse.
disableDrag	boolean or function	false	Disable dragging. Pass boolean to apply to all items. Pass a callback to target individual items. It has a single parameter with keys: item - item from your array, index - number, index of the item, depth - number, depth of the item.
group	string or number	random string	Different group names may be passed if you have more than one nestable component on a page and want some extra styles for portal instances.
handler	node	undefined	If you pass it, it will get wrapped with drag handlers and you may use it in your render method.
idProp	string	"id"	Name of a property for id.
items	array	[]	Array of items. Every item must be of shape {id: @uniq} to distinguish elements.
maxDepth	number	10	Maximum available level of nesting.
onChange	function	() => {}	Callback which has a single parameter with keys: items - new array after position was changed, dragItem - item which has been moved, targetPath - array of numbers, those numbers are indices and they make path to a location, to where item has been moved.
onCollapseChange	function	() => {}	Callback which has a single parameter with one of two possible keys: openIds - array of ids which are open if collapsed is set to ture, or closedIds - array of ids which are closed if collapsed is set to false. Note: this callback is triggered not only when user explicitly opens or closes an item, but when implicit events happen as well, like when the only child of open item is moved out.
onDragEnd	function	() => {}	Callback which has no parameters. It is invoked when dragging ends via drop or cancel.
onDragStart	function	() => {}	Callback which has a single parameter with keys: dragItem - item which has been moved.
renderCollapseIcon	function	() => <DefaultIcon />	Function for rendering collapse icon. Has a single parameter with keys: isCollapsed - boolean, true if this group has children and is collapsed, item - item from your array.
renderItem	function	({item}) => String(item)	Function for rendering every item. Has a single parameter with keys: item - item from your array, index - number, index of the item, depth - number, depth of the item, collapseIcon - node, icon for items with children (allows you to collapse the group), handler - node, which you have passed via the same property, but wrapped with some additional events, isDraggable - boolean, tells if dragging is allowed for this item (see disableDrag prop for details).
threshold	number	30	Amount of pixels which mouse should move horizontally before increasing/decreasing level (nesting) of current element.
