    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
    
    // 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:

    key Type Default Description
    ariaLabel string null Aria Label to be applied to the option
    className string null CSS class to be applied to this option
    title string null HTML title to be used for the option
    value string null The 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.

    Custom styling can be applied using CSS className props (As seen in props table below)
