MultiSelect — Frontfriend

Interactive preview

Rendered from the shared Frontfriend stories with React Base, the same preview Studio shows. Styling comes from your Design System; the code below is native to Radix UI.

Installation

Complete project setup first. Your configuration must select react/radix and include your Design System ID.

pnpm exec frontfriend download multi-select -f react --primitive radix

Usage

import { MultiSelect } from "@/components/ui/multi-select";
import * as React from "react";
const countryList = [
  { value: "italy", label: "Italy", keywords: ["roma", "it"] },
  { value: "uk", label: "United Kingdom", keywords: ["britain", "gb"] },
  { value: "france", label: "France", keywords: ["paris", "fr"] },
  { value: "germany", label: "Germany", keywords: ["berlin", "de"] },
  { value: "usa", label: "United States", keywords: ["america", "us"] },
];
const TRIGGER_WIDTH = "min-w-[260px] w-auto";
export default function MultiSelectExample() {
  const [value, setValue] = React.useState(["italy", "uk"]);
  return (
    <MultiSelect
      placeholder="Select..." maxCount={3} selectAll={false} clearable createNew={false} batchCreate={false} searchPlaceholder="Search..." closeOnSelect={false} options={countryList} className={TRIGGER_WIDTH}
      value={value}
      onValueChange={setValue}
    />
  );
}

Behavior

createNew and batchCreate are opt-in; batchCreate is inactive when createNew is false.
Batch creation uses comma, semicolon, tab, and newline separators. Paste with a separator is processed immediately; typed batches are processed on Enter or Create new.
normalizeNewValue applies only to new candidates before empty checks, validation, deduplication, and insertion.
validateNewValue is synchronous and runs per normalized candidate. onCreateNew runs only after a new option is accepted.
Valid unique candidates are retained when other batch candidates are invalid or duplicated; value bindings update once per batch.
Existing unselected options are selected rather than recreated; existing selected values and repeated normalized candidates count as duplicates.
options remains authoritative. Created selected values render with label ?? value and do not warn or become persistent searchable options until the consumer adds them to options.
Search is trimmed, case-insensitive, diacritic-insensitive substring matching over label, value, and keywords, with one target-native filtering pass and no public custom filter callback.
Filtered Select all adds missing visible options while preserving hidden selections; when every visible option is selected it removes only visible options.
Batch validation errors remain visible after partial success. Duplicate-only batches show duplicateErrorMessage; mixed successful batches report duplicates through announcements without a visual duplicate error.
The list exposes listbox semantics and rows expose option plus aria-selected. Internal checkboxes and icons are decorative; ariaLabel falls back to label.
Announcements have English defaults and accept partial semantic formatter overrides without hardcoded selected/not-selected text in option labels.
closeOnSelect closes only after selecting a previously unselected option; deselection keeps the popover open.
