Installation

npm i react-bootstrap-tree-editor

Quick Start

It's highly recommended you check out the demo and its source to quickly get yourself up and running.

Import the following:

import {
  BasicTreeNodeComponent,
  defaultTreeControllerOptions,
  defaultTreeData,
  useTreeController,
  useTreeShortcuts,
  useTreeState,
} from 'react-bootstrap-tree-editor';

Inside your function component:

const treeOptions = defaultTreeControllerOptions;
const [tree, setTree] = useTreeState(defaultTreeData);
const treeController = useTreeController(tree, setTree, treeOptions);
const shortcuts = useTreeShortcuts(treeController, document);

// Ensure there's always at least one item to edit
React.useEffect(() => {
  if (!treeController.tree.hasChildren()) {
    const newNodeData = treeController.options.createNewData();
    const node = treeController.mutations.addChildNodeData(treeController.tree, newNodeData);
    treeController.focus.setFocusedNode(node);
  }
}, [treeController.focus, treeController.mutations, treeController.tree, treeController.options]);

Render the component:

<BasicTreeNodeComponent
  node={treeController.tree}
  treeController={treeController}
  editable={true}
  shortcuts={shortcuts}
  showBullets={false}
  showPointer={false}
/>

Setting Tree Data Externally

If you'd like to set the tree data yourself outside of the editor, then you'll need to force the tree node component to re-render when you set the data.

To do this, you can create a piece of state called changeTime that tracks when you set the data yourself. You'd then pass this value as the key prop to the BasicTreeNodeComponent.

// Use this to force tree to re-render when setting tree data
const [changeTime, setChangeTime] = React.useState(Date.now());

const resetTree = () => {
  const newTree = new Tree(defaultTreeData);
  // Track when we changed the tree data ourselves
  setChangeTime(Date.now());
  setTree(newTree);
}

Add the key prop to BasicTreeNodeComponent, using the changeTime as the value:

<BasicTreeNodeComponent
  key={changeTime} // Ensures external changes to tree data are rendered
  node={treeController.tree}
  treeController={treeController}
  editable={true}
  shortcuts={shortcuts}
  showBullets={false}
  showPointer={false}
/>

Now you can modify the tree using both the editor, and externally.
