Use tree components to display hierarchical structures like file systems, project directories, or nested content. The tree component supports keyboard navigation and accessibility features.

Create trees with either a Markdown list or the `Tree.Folder` and `Tree.File` components. `<Tree>` and `<FileTree>` are aliases, so either tag works with either syntax.

Use the Markdown list syntax for quick, static trees where every folder can expand by default. Use the component syntax when you need to control open state per folder with `defaultOpen`, mark folders as non-interactive with `openable`, or mix files and folders at arbitrary depth.

## Markdown list syntax [#markdown-list-syntax]

Write a nested Markdown list inside `<FileTree>` (or `<Tree>`) to describe a folder structure. Add a trailing slash to mark a folder, or nest items under it. Folders that contain nested items expand by default.

<FileTree>
  * docs/
    * index.mdx
    * guides/
      * configuration.mdx
  * docs.config.ts
</FileTree>

```mdx title="File tree example"
<FileTree>

- docs/
  - index.mdx
  - guides/
    - configuration.mdx
- docs.config.ts

</FileTree>
```

Leave a blank line after the opening tag and before the closing tag so that the list parses as Markdown. Names strip inline formatting like `` `code` ``, `**bold**`, or `_italic_`.

## Basic tree [#basic-tree]

<Tree>
  <Tree.Folder name="app">
    <Tree.File name="layout.tsx" />

    <Tree.File name="page.tsx" />

    <Tree.File name="global.css" />
  </Tree.Folder>

  <Tree.Folder name="lib">
    <Tree.File name="utils.ts" />

    <Tree.File name="db.ts" />
  </Tree.Folder>

  <Tree.File name="package.json" />

  <Tree.File name="tsconfig.json" />
</Tree>

```mdx title="Tree example"
<Tree>
  <Tree.Folder name="app" defaultOpen>
    <Tree.File name="layout.tsx" />
    <Tree.File name="page.tsx" />
    <Tree.File name="global.css" />
  </Tree.Folder>
  <Tree.Folder name="lib">
    <Tree.File name="utils.ts" />
    <Tree.File name="db.ts" />
  </Tree.Folder>
  <Tree.File name="package.json" />
  <Tree.File name="tsconfig.json" />
</Tree>
```

## Nested folders [#nested-folders]

Create deeply nested structures by nesting `Tree.Folder` components within each other.

<Tree>
  <Tree.Folder name="app">
    <Tree.File name="layout.tsx" />

    <Tree.File name="page.tsx" />

    <Tree.Folder name="api">
      <Tree.Folder name="auth">
        <Tree.File name="route.ts" />
      </Tree.Folder>

      <Tree.File name="route.ts" />
    </Tree.Folder>

    <Tree.Folder name="components">
      <Tree.File name="button.tsx" />

      <Tree.File name="dialog.tsx" />

      <Tree.File name="tabs.tsx" />
    </Tree.Folder>
  </Tree.Folder>

  <Tree.File name="package.json" />
</Tree>

```mdx title="Nested folders example"
<Tree>
  <Tree.Folder name="app" defaultOpen>
    <Tree.File name="layout.tsx" />
    <Tree.File name="page.tsx" />
    <Tree.Folder name="api" defaultOpen>
      <Tree.Folder name="auth">
        <Tree.File name="route.ts" />
      </Tree.Folder>
      <Tree.File name="route.ts" />
    </Tree.Folder>
    <Tree.Folder name="components">
      <Tree.File name="button.tsx" />
      <Tree.File name="dialog.tsx" />
      <Tree.File name="tabs.tsx" />
    </Tree.Folder>
  </Tree.Folder>
  <Tree.File name="package.json" />
</Tree>
```

## Highlight the active path [#highlight-the-active-path]

Add the `highlight` property to `Tree.File` or `Tree.Folder` to mark the current item. Use it to draw attention to a file or folder you reference in nearby prose, such as the file a reader should open next.

Highlighting a folder also tints its descendants, so the active path stands out.

<Tree>
  <Tree.Folder name="app">
    <Tree.File name="layout.tsx" />

    <Tree.File name="page.tsx" />

    <Tree.Folder name="api">
      <Tree.File name="route.ts" />
    </Tree.Folder>
  </Tree.Folder>

  <Tree.File name="package.json" />
</Tree>

```mdx title="Highlighted tree example"
<Tree>
  <Tree.Folder name="app" defaultOpen>
    <Tree.File name="layout.tsx" />
    <Tree.File name="page.tsx" highlight />
    <Tree.Folder name="api" defaultOpen highlight>
      <Tree.File name="route.ts" />
    </Tree.Folder>
  </Tree.Folder>
  <Tree.File name="package.json" />
</Tree>
```

### Customize the highlight color [#customize-the-highlight-color]

The `--tree-highlight` CSS variable defines the highlight color. Set it on the `Tree` root component to override the color for that tree.

```mdx title="Custom highlight color"
<Tree style={{ "--tree-highlight": "rgb(59 130 246)" }}>
  <Tree.Folder name="app" defaultOpen>
    <Tree.File name="page.tsx" highlight />
  </Tree.Folder>
</Tree>
```

## Keyboard navigation [#keyboard-navigation]

The tree component supports keyboard navigation.

* **Arrow keys**: Navigate up and down through visible items.
* **Right arrow**: Expand a closed folder or move to the first child of an open folder.
* **Left arrow**: Collapse an open folder or move to the parent folder.
* **Home**: Jump to the first item in the tree.
* **End**: Jump to the last visible item in the tree.
* **Enter/Space**: Toggle folder open/closed state.
* **\***: Expand all sibling folders at the current level.
* **Type-ahead search**: Type characters to jump to items that start with those characters.
