MUI Tree Select

Description

A MUI v5 compatible select that provides a compact user interface for navigating a tree structures.

Usage

Given the following tree node interface.

class Node {
  constructor(value, parent = null, children = null) {
    this.value = value;
    this.parent = parent;
    this.children = children;
  }
}

1. Implement a getChildren method to tell Tree Select how to retrieve child nodes.

const rootNodes = [...] // Array of Nodes;
const getChildren = (node) => node === null ? rootNodes : node.children;

2. Implement a getParent method to tell Tree Select how to retrieve parent nodes.

const getParent = (node) => node.parent;

3. Implement a renderInput method required by Autocomplete.

const renderInput = (params) => <TextField {...params} />;

4. Pass to the MUI Tree Select.

return <TreeSelect
  getChildren={getChildren}
  getParent={getParent}
  renderInput={renderInput}
/>;

Notes

Autocomplete

This package wraps the MUI Autocomplete component. Many of props from this component are passed from TreeSelect.

FreeSoloNode

freeSolo values are wrapped in the class FreeSoloNode to provided a reference to the parent node under which the free solo value was created.

FreeSoloNode extends the native String object. This disallows "es5" as a target based on the way the typescript transpiler converts class semantics to function.
