Usage

{{ariaListbox}}

Basic example:

import { ariaListbox } from 'ember-aria-voyager';
const options = ['apple', 'banana', 'pineapple'];

<template>
  <ul role="listbox" {{ariaListbox items=options}}>
    {{#each options as |option|}}
      <li role="option">{{option}}</li>
    {{/each}}
  </ul>
</template>

Here are the options, you can pass to {{ariaListbox}}

type ListboxSignature<T = HTMLElement> = {
  items?: T[];
  selection?: T | T[];
  activateItem?: (item: T) => void;
} & (
  | {
      multi: true;
      select?: (selection: T[]) => void;
    }
  | {
      multi?: false;
      select?: (selection: T) => void;
    }
)

When passing items the select() and selection can work off of your passed items, anyway will fall back to the HTMLElement

Full example:

import { ariaListbox } from 'ember-aria-voyager';
const options = ['apple', 'banana', 'pineapple'];
const context = new class {
  @tracked selection = [options[0]];

  select: (fruits: string[]) => {
    this.selection = fruits;
  }
};

const selection = ['banana'];

<template>
  <ul role="listbox" {{ariaListbox 
    items=options
    multi=true
    disabled=context.disabled
    selection=context.selection
