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

Changelog

If you want to support React version under v0.13, use react-dropdown@v0.6.1

Usage

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

Mount

import Dropdown from 'react-dropdown'
import 'react-dropdown/style.css'
const defaultOption = options[0]
<Dropdown options={options} onChange={this._onSelect} value={defaultOption} placeholder="Select an option" />

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" />

Custom className

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

<Dropdown className='myClassName' />

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

<Dropdown controlClassName='myControlClassName' />

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

<Dropdown placeholderClassName='myPlaceholderClassName' />

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' />

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

<Dropdown arrowClassName='myArrowClassName' />

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" />}
/>
