Demo And Examples

For demo and examples see https://jfangrad.github.io/react-dropdown-aria/

Installation

Simply use npm or yarn to install the package.

// Yarn
$ yarn add react-dropdown-aria styled-components

// npm
$ npm install --save react-dropdown-aria styled-components

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:

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.

Styling

Custom styling can be applied to the dropdown through 2 ways: 1. CSS className props (As seen in props table below) 2. JavaScript Objects passed to the theme prop (Example) 3. Using the styled-components library (Example)

Option 1

The suggested method is by using the theme prop as shown in the Custom Styling Example. The theme prop can have keys of the following form:

type RdaTheme = {
  wrapper?: ThemeObjectOrFunction<DropdownWrapperProps>;
  selector?: ThemeObjectOrFunction<DropdownSelectorProps>;
  selectorSearch?: ThemeObjectOrFunction;
  selectedValue?: ThemeObjectOrFunction<SelectedValueProps>;
  placeholder?: ThemeObjectOrFunction<PlaceholderProps>;
  arrow?: ThemeObjectOrFunction<ArrowProps>;
  optionContainer?: ThemeObjectOrFunction<OptionContainerProps>;
  groupContainer?: ThemeObjectOrFunction;
  groupHeading?: ThemeObjectOrFunction;
  groupDivider?: ThemeObjectOrFunction;
  optionItem?: ThemeObjectOrFunction<OptionItemWrapProps>;
};

As is shown above, each key in the theme object can be either a plain object or function. If you need access to the current state of the dropdown then you should pass a function which will be called with the appropiate state. The theme object you provide will be merged with the default theme.

option 3

If you would prefer to use option 3, you can apply styles to the sub components of the dropdown using the method described here. The sub components can be imported via

import { StyledDropdownComponents } from 'react-dropdown-aria';

Each component is a property on that import and has the same keys as those listed above using typical component casing. (Example)
