Installation

Simply use npm or yarn to install the package.

// Yarn
$ yarn add react-dropdown-aria
// npm
$ npm install --save react-dropdown-aria

You can then include it in your project as needed:

import Dropdown from 'react-dropdown-aria';

Usage

Options should be provided to the Dropdown as an array of objects.

Simple Example:

<Dropdown
  ...
  options: {[
    { value: 'one' },
    { value: 'two' },
    { value: 'three' }
  ]}
/>

Each option object in the array of options can have the following keys:

keyTypeDefaultDescription
ariaLabelstringnullAria Label to be applied to the option
classNamestringnullCSS class to be applied to this option
titlestringnullHTML title to be used for the option
valuestringnullThe value to be displayed in the dropdown (Required)

Groups Example

Groups of items can also be implemented by pasing an array of objects of the following form to the dropdown options prop:

<Dropdown
  ...
  options: {[
    { label: 'Group 1', groupOptions: optionsGroup1 },
    { label: 'Group 2', groupOptions: optionsGroup2 },
  ]}
/>

Where the groupOptions is an array of options as described above, and the label is the string to display above the group in the dropdown.
