(react-dropdown
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
Changelog
If you want to support React version under v0.13, use react-dropdown@v0.6.1
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" />}
/>;
