# Install and place "combobox-020" (Narrow Column) 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/combobox-020.json
Registry item: https://vibeui.ru/r/combobox-020.json
Installs to: components/vibeui/combobox-020.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
A picker for a narrow column where the list truncates on the right while the selected value truncates in the middle, keeping both its head and its tail.
A picker for tight places: a sidebar, a table cell, a side panel. Long values are truncated two different ways — the list is cut on the right because it is read from the start, and the selected value is cut in the middle because the tail of a branch, path or filename is what distinguishes it. The full text stays available in title, in aria-label and as a line below. Zero dependencies, one file, its own palette.
## 3. How to use it
import { Combobox020 } from "@/components/vibeui/combobox-020"
<Combobox020 headChars={14} tailChars={10} />
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-combobox-020-* palette — do not swap it for your theme tokens (bg-muted, text-muted-foreground and the like)
- the two different truncation strategies for the list and for the value: that is the substance of this variant, not decoration
- the shorten helper with a middle ellipsis — a plain ellipsis eats the tail, and the tail is what tells similar values apart
- the aria-label carrying the full text on each option: a screen reader must not read a truncated string
- the full text below with overflow-wrap: anywhere — the only place the value is visible in full without hovering
- the title on list rows: checking a full name with the mouse must not require selecting it
- the monospace font on values only: identical prefixes line up into a column and diverge faster to the eye
## 6. You may change
- label — the field caption; placeholder — the hint in the filter field
- options — the list of values
- defaultValue — the value selected at first render
- headChars — how many characters to keep at the start when truncating in the middle
- tailChars — how many characters to keep at the tail
- onSelect — the selection handler; accent — the selected-row colour
## 7. Rules
- Do not raise max-width so “it all fits”: the point of this variant is that space is scarce and will stay scarce.
- title does not appear on touch devices: the full line below is not duplication, it is the only way to read the value on a phone.
- Truncation counts characters, not pixels: in a wide font a 14-character head may not be enough, tune it to your typeface.
- Do not truncate list rows in the middle: there the priority is scanning the beginnings, not tail uniqueness.
## 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/combobox-020.jsonhttps://vibeui.ru/r/combobox-020.jsonКомпонент самодостаточен: один файл, ноль зависимостей, собственная палитра в локальных переменных --vibeui-combobox-020-*. Клиентский: запрос и значение живут в useState. Ширина ограничена 15rem — это ячейка таблицы, колонка сайдбара или боковая панель. Обрезка сделана двумя разными способами осознанно: строки списка режутся средствами CSS (white-space: nowrap + text-overflow: ellipsis), потому что список читают с начала; выбранное значение режется функцией shorten по середине, потому что у пути, ветки или файла значим хвост. Полный текст никуда не теряется: он лежит в title каждой строки, в aria-label варианта и целиком выводится внизу с overflow-wrap: anywhere. Моноширинный шрифт включён только для значений — так одинаковые префиксы визуально выстраиваются в столбец.
Component source
The same file your agent installs. Here in case you would rather copy it by hand.

// Идея компонента: в узкой колонке — сайдбар, ячейка таблицы, боковая
// панель — длинные значения обрезаются, и обрезать их надо по-разному.
// В списке читают с начала, поэтому строки гаснут многоточием справа.
// А у выбранного значения важен хвост: имя файла, окончание пути, номер
// версии, — поэтому оно режется по середине и сохраняет оба конца.
