## Try It

Edit the code below to experiment with the component:

```tsx live
function Demo() {
  const [value, setValue] = React.useState(undefined);
  const treeData = [
    {
      title: 'Databases',
      value: 'databases',
      children: [
        { title: 'PostgreSQL', value: 'postgres' },
        { title: 'MySQL', value: 'mysql' },
      ],
    },
    {
      title: 'Charts',
      value: 'charts',
      children: [
        { title: 'Bar Chart', value: 'bar' },
        { title: 'Line Chart', value: 'line' },
      ],
    },
  ];
  return (
    <TreeSelect
      style={{ width: 300 }}
      value={value}
      onChange={setValue}
      treeData={treeData}
      placeholder="Select an item"
      allowClear
      treeDefaultExpandAll
    />
  );
}
```

## Multiple Selection with Checkboxes

```tsx live
function MultiSelectTree() {
  const [value, setValue] = React.useState([]);
  const treeData = [
    {
      title: 'Databases',
      value: 'databases',
      children: [
        { title: 'PostgreSQL', value: 'postgres' },
        { title: 'MySQL', value: 'mysql' },
        { title: 'SQLite', value: 'sqlite' },
      ],
    },
    {
      title: 'File Formats',
      value: 'formats',
      children: [
        { title: 'CSV', value: 'csv' },
        { title: 'Excel', value: 'excel' },
      ],
    },
  ];
  return (
    <TreeSelect
      style={{ width: 300 }}
      value={value}
      onChange={setValue}
      treeData={treeData}
      treeCheckable
      placeholder="Select data sources"
      treeDefaultExpandAll
      allowClear
    />
  );
}
```

## With Tree Lines

```tsx live
function TreeLinesDemo() {
  const treeData = [
    {
      title: 'Dashboards',
      value: 'dashboards',
      children: [
        { title: 'Sales Dashboard', value: 'sales' },

        { title: 'Revenue Chart', value: 'revenue' },
        { title: 'User Growth', value: 'growth' },
      ],
    },
  ];
  return (
    <TreeSelect
      style={{ width: 300 }}
      treeData={treeData}
      treeLine
      treeDefaultExpandAll
      placeholder="Browse items"
    />
