Seleção

Um menu suspenso pra escolher uma opção — campos de país, ordens de classificação, configurações de tema — com bordas grossas no estilo neobrutalista e sombras marcantes.

import {
  Select,
  SelectContent,

O select abre uma lista de opções em um popup e mostra a escolhida no trigger — um substituto estilizado e pronto para formulários do <select> nativo. Construído sobre o componente Base UI Select e estilizado com a receita neobrutalista: bordas grossas, sombras duras e tipografia em negrito.

Quando usar:

Campos de formulário com opções fixas — país, moeda, fuso horário; qualquer lugar onde você usaria um <select> nativo.
Controles de ordenação e filtro — ordene uma grade de produtos ou uma tabela por preço, data ou popularidade.
Seletores de preferência — tema, idioma ou frequência de notificações em um painel de configurações.

Atualize os caminhos de importação conforme a configuração do seu projeto.

Uso

import {
  Select,
  SelectContent,
  SelectGroup,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@/components/ui/select"

const items = [
  { label: "Light", value: "light" },
  { label: "Dark", value: "dark" },
  { label: "System", value: "system" },
]
 
<Select items={items}>
  <SelectTrigger className="w-[180px]">
    <SelectValue placeholder="Theme" />
  </SelectTrigger>
  <SelectContent>
    <SelectGroup>
      {items.map((item) => (
        <SelectItem key={item.value} value={item.value}>
          {item.label}
        </SelectItem>
      ))}
    </SelectGroup>
  </SelectContent>
</Select>

Composição

Use a seguinte composição para construir um Select:

Select
├── SelectTrigger
│   └── SelectValue
└── SelectContent
    ├── SelectGroup
    │   ├── SelectLabel
    │   ├── SelectItem
    │   └── SelectItem
    ├── SelectSeparator
    └── SelectGroup
        ├── SelectLabel
        ├── SelectItem
        └── SelectItem

Exemplos

Alinhamento do item com o gatilho

Use alignItemWithTrigger em SelectContent para controlar se o item selecionado se alinha com o gatilho. Quando true (padrão), o popup se posiciona de forma que o item selecionado aparece sobre o gatilho. Quando false, o popup se alinha com a borda do gatilho.

Align Item

Toggle to align the item with the trigger.

"use client"

import * as React from "react"

Grupos

Use SelectGroup, SelectLabel e SelectSeparator para organizar os itens.

import {
  Select,
  SelectContent,

Com rolagem

Um select com muitos itens que pode ser rolado.

import {
  Select,
  SelectContent,

Desabilitado

import {
  Select,
  SelectContent,

Inválido

Adicione o atributo data-invalid ao componente Field e o atributo aria-invalid ao componente SelectTrigger para exibir um estado de erro.

<Field data-invalid>
  <FieldLabel>Fruit</FieldLabel>
  <SelectTrigger aria-invalid>
    <SelectValue />
  </SelectTrigger>
</Field>

import { Field, FieldError, FieldLabel } from "@/components/ui/field"
import {
  Select,

RTL

Para ativar o suporte a RTL no Neobrutalism, consulte o guia de configuração de RTL.

"use client"

import * as React from "react"

Acessibilidade

O select implementa o padrão Combobox do WAI-ARIA na sua forma somente de seleção: o trigger é anunciado como um combobox recolhido com aria-expanded, o popup renderiza como um listbox de itens option, e aria-selected acompanha o valor atual — tudo conectado pela primitiva.

Interações de teclado:

Tecla	Ação
`Space` / `Enter`	Abre o select; com ele aberto, seleciona o item destacado
`ArrowDown` / `ArrowUp`	Abre quando fechado; aberto, destaca o item seguinte / anterior
`Esc`	Fecha o popup e devolve o foco ao trigger
Digitar caracteres	Typeahead — salta para o primeiro item correspondente
