react-dropdown-browser

Note This is a minimally modified fork of fraserxu/react-dropdown, with the addition of a browser build, so that the library can be used from a CDN. This fork will become deprecated if this pull request is merged: Add browser build #174. Content below is the original README. -- Curran

Simple Dropdown component for React, inspired by react-select Demo is available here

Why

• The default HTML select element is hard to style
• And sometime we also want grouped menus
• if you want more advanced select, check react-select

Installation

// with npm
$ npm install react-dropdown  --save

// with yarn
$ yarn add react-dropdown

Usage

This is the basic usage of react-dropdown

import Dropdown from 'react-dropdown';
import 'react-dropdown/style.css';

const options = [
  'one', 'two', 'three'
];
const defaultOption = options[0];
<Dropdown options={options} onChange={this._onSelect} value={defaultOption} placeholder="Select an option" />;

Options

Flat Array options

const options = [
  'one', 'two', 'three'
];

Object Array options

const options = [
  { value: 'one', label: 'One' },
  { value: 'two', label: 'Two', className: 'myOptionClassName' },
  {
   type: 'group', name: 'group1', items: [
     { value: 'three', label: 'Three', className: 'myOptionClassName' },
     { value: 'four', label: 'Four' }
   ]
  },
  {
   type: 'group', name: 'group2', items: [
     { value: 'five', label: 'Five' },
     { value: 'six', label: 'Six' }
   ]
  }
];

When using Object options you can add to each option a className string to further customize the dropdown, e.g. adding icons to options

Disabling the Dropdown

Just pass a disabled boolean value to the Dropdown to disable it. This will also give you a .Dropdown-disabled class on the element, so you can style it yourself.

<Dropdown disabled onChange={this._onSelect} value={defaultOption} placeholder="Select an option" />;

Customizing the dropdown

className

The className prop is passed down to the wrapper div, which also has the Dropdown-root class.

<Dropdown className='myClassName' />;

controlClassName

The controlClassName prop is passed down to the control div, which also has the Dropdown-control class.

<Dropdown controlClassName='myControlClassName' />;

placeholderClassName

The placeholderClassName prop is passed down to the placeholder div, which also has the Dropdown-placeholder class.

<Dropdown placeholderClassName='myPlaceholderClassName' />;

menuClassName

The menuClassName prop is passed down to the menu div (the one that opens and closes and holds the options), which also has the Dropdown-menu class.

<Dropdown menuClassName='myMenuClassName' />;

arrowClassName

The arrowClassName prop is passed down to the arrow span , which also has the Dropdown-arrow class.

<Dropdown arrowClassName='myArrowClassName' />;

arrowClosed, arrowOpen

The arrowClosed & arrowOpen props enable passing in custom elements for the open/closed state arrows.

<Dropdown
  arrowClosed={<span className="arrow-closed" />}
  arrowOpen={<span className="arrow-open" />}
/>;
