Select

Displays a native list of options for the user to pick from.

Areia's Select uses the platform <select> primitive, so it keeps native keyboard, form, and mobile behavior while adding Areia styling and field helpers.

Fruit

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="fruit"
    label="Fruit"
    value="apple"
    items={{
      apple: "Apple",
      banana: "Banana",
      cherry: "Cherry",
    }}
  />
));

Import

import { Select } from "areia";

Usage

Plan

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="plan"
    label="Plan"
    placeholder="Choose a plan"
    items={{
      free: "Free",
      pro: "Pro",
      team: "Team",
    }}
  />
));

Examples

Basic

A select with a visible label. When you provide the label prop, the select renders with a field wrapper and label above it.

Fruit

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="basic-fruit"
    label="Fruit"
    value="apple"
    items={{
      apple: "Apple",
      banana: "Banana",
      cherry: "Cherry",
    }}
  />
));

Sizes

Use the size prop to match Input sizing: xs, sm, base, and lg.

import ilha from "ilha";
import { Select } from "areia";

const items = {
  apple: "Apple",
  banana: "Banana",
  cherry: "Cherry",
};

export default ilha.render(() => (
  <div class="flex w-full max-w-sm flex-col gap-3">
    <Select
      size="xs"
      aria-label="Extra small select"
      value="apple"
      items={items}
    />
    <Select
      size="sm"
      aria-label="Small select"
      value="apple"
      items={items}
    />
    <Select
      size="base"
      aria-label="Base select"
      value="apple"
      items={items}
    />
    <Select
      size="lg"
      aria-label="Large select"
      value="apple"
      items={items}
    />
  </div>
));

Without Visible Label

When a visible label is not needed, use aria-label for accessibility.

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    aria-label="Select fruit"
    value="banana"
    items={{
      apple: "Apple",
      banana: "Banana",
      cherry: "Cherry",
    }}
  />
));

With Description and Error

Select can show description text and validation errors. Error styling is automatically applied when the error prop is truthy.

Issue type

Choose the category that best matches your report.

Select an issue type before continuing.

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="issue-type"
    label="Issue type"
    description="Choose the category that best matches your report."
    error="Select an issue type before continuing."
    placeholder="Choose an issue type"
    items={{
      bug: "Bug",
      documentation: "Documentation",
      feature: "Feature",
    }}
  />
));

Placeholder

Use the placeholder prop to render a placeholder option before the selectable items.

Priority

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="priority"
    label="Priority"
    placeholder="Choose priority"
    items={{
      low: "Low",
      medium: "Medium",
      high: "High",
      critical: "Critical",
    }}
  />
));

Use labelTooltip to add additional context via a native title attribute on the label.

Severity

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="severity"
    label="Severity"
    labelTooltip="Choose the highest impact level that applies."
    placeholder="Choose severity"
    items={{
      low: "Low",
      medium: "Medium",
      high: "High",
      critical: "Critical",
    }}
  />
));

Disabled

Fruit

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    label="Fruit"
    disabled
    value="apple"
    items={{
      apple: "Apple",
      banana: "Banana",
      cherry: "Cherry",
    }}
  />
));

Multiple Selection

Enable native multiple selection with the multiple prop. The select becomes a multi-row native control.

Columns

Hold Command or Control to select multiple options.

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="columns"
    label="Columns"
    multiple
    description="Hold Command or Control to select multiple options."
    items={{
      name: "Name",
      location: "Location",
      size: "Size",
      read: "Read",
      write: "Write",
      createdAt: "Created At",
    }}
  />
));

Disabled Options

Options can be disabled with descriptor objects in the items prop.

Plan

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="plan-disabled"
    label="Plan"
    value="free"
    items={{
      free: "Free",
      pro: "Pro",
      business: { label: "Business", disabled: true },
      enterprise: { label: "Enterprise", disabled: true },
    }}
  />
));

Options as Children

Use Select.Option when you want explicit control over individual option markup.

Fruit

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="explicit-options"
    label="Fruit"
    placeholder="Choose fruit"
  >
    <Select.Option value="apple" label="Apple" />
    <Select.Option value="banana" label="Banana" />
    <Select.Option value="cherry" label="Cherry" />
  </Select>
));

Grouped Options

Use Select.Group to organize related options under native optgroup labels.

Food

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    id="grouped-food"
    label="Food"
    placeholder="Choose food"
  >
    <Select.Group label="Fruits">
      <Select.Option value="apple" label="Apple" />
      <Select.Option value="banana" label="Banana" />
    </Select.Group>
    <Select.Group label="Vegetables">
      <Select.Option value="carrot" label="Carrot" />
      <Select.Option value="lettuce" label="Lettuce" />
    </Select.Group>
  </Select>
));

Ghost Variant

Use variant: "ghost" for compact UIs where the select should blend into the surrounding surface.

import ilha from "ilha";
import { Select } from "areia";

export default ilha.render(() => (
  <Select
    variant="ghost"
    aria-label="Sort by"
    value="updated"
    items={{
      updated: "Recently updated",
      created: "Recently created",
      name: "Name",
    }}
  />
));

Accessibility

Label Requirement

Selects should have an accessible name via one of:

label prop
aria-label for selects without a visible label
aria-labelledby for custom label association

Native Behavior

Because Select uses the native <select> primitive, it keeps browser-provided keyboard navigation, form submission, and mobile picker behavior.

Error Association

When an id is provided, descriptions and error messages are automatically associated with the select using aria-describedby.
