Guide Line Tree

An expanded structure with real guide lines: on the last node of a branch the vertical is cut to the elbow's height, so the line ends there instead of trailing into empty space.

  2. 2. Write to your agent in your own words and drop the link into the sentence.
  3. 3. The agent opens the link and installs the component from the registry.

# Install and place "tree-008" (Guide Line Tree) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/tree-008.json

Registry item: https://vibeui.ru/r/tree-008.json
Installs to: components/vibeui/tree-008.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
An expanded structure with real guide lines: on the last node of a branch the vertical is cut to the elbow's height, so the line ends there instead of trailing into empty space.

An expanded structure with level guides: the elbows are drawn by pseudo-elements, with no box-drawing characters in the text. Zero dependencies, one file, server rendered.

## 3. How to use it
import { Tree008 } from "@/components/vibeui/tree-008"

<Tree008
  label="Package contents"
  nodes={[{ name: "dist", note: "412 KB", children: [{ name: "index.js", note: "184 KB" }] }]}
/>

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-tree-008-* palette — do not swap it for your theme tokens
- cutting the vertical on the last node: without it the line trails into empty space
- drawing the elbows with pseudo-elements rather than ├ and └ — those end up in the clipboard on copy
- the row height in a variable: the elbow position is measured from it
- the tree, treeitem and group roles with aria-level: the lines draw structure for the eye only
- its own light surface: without it the dark names disappear on a dark background

## 6. You may change
- the structure through nodes, including the note on a node
- the tree caption through label
- the guide colour and weight through the line variable
- the level indent through the indent variable

## 7. Rules
- The tree is always expanded: there is no collapsing, this is a structure display, not navigation.
- A multiline name breaks the elbow position: it is measured from a fixed row height.
- aria-expanded on branches is always true — as it should be, there is nothing to collapse them with.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/tree-008.json
https://vibeui.ru/r/tree-008.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-tree-008-*. Серверный: хуков нет, дерево всегда развёрнуто. Уголок рисуют два псевдоэлемента узла: ::before — вертикаль ветки, ::after — поперечина на середине строки; у :last-child вертикаль укорачивается до половины строки, и получается ровно то, что печатает команда tree в терминале. Псевдографика не уходит в текст: символы ├ и └ попали бы в буфер обмена при копировании имён. Высота строки вынесена в переменную, потому что от неё считается положение поперечины. Роли tree, treeitem и group с aria-level описывают структуру, aria-expanded на ветках объявлено постоянно истинным.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Tree008Node = {
  name: string
  note?: string
  children?: Tree008Node[]
}

export type Tree008Props = Omit<ComponentPropsWithoutRef<"div">, "children"> & {
  nodes?: Tree008Node[]
  label?: string
}

// Идея компонента: развёрнутая структура с настоящими направляющими. Уголок
// каждого узла рисуют два псевдоэлемента — вертикаль и поперечина, — а у
// последнего в ветке вертикаль обрезается по высоте уголка, поэтому линия
// заканчивается на нём, а не уходит в пустоту. Это ровно то, что печатает
// tree в терминале, но без псевдографики в тексте: символы ├ и └ уехали бы
// в буфер обмена при копировании имён.
