React-Select-Plus

A fork of JedWatson/React-Select with support for option groups.

🚨 Project status 🚨

This fork is no longer actively maintained. The primary purpose of this project was to add option group support to react-select, a feature that will be supported in the upcoming react-select 2.0. Another alternative worth checking out is downshift, which provides low-level building blocks for building custom dropdown components.

Demo & Examples

Live demo: github.hubspot.com/react-select-plus/

Installation

The easiest way to use react-select is to install it from npm and build it into your app with Webpack.

yarn add react-select-plus

You can then import react-select-plus and its styles in your application as follows:

import Select from 'react-select-plus';
import 'react-select-plus/dist/react-select-plus.css';

You can also use the standalone UMD build by including dist/react-select-plus.js and dist/react-select-plus.css in your page. If you do this you'll also need to include the dependencies. For example:

<script src="https://unpkg.com/[email protected]/dist/react.js"></script>
<script src="https://unpkg.com/[email protected]/dist/react-dom.js"></script>
<script src="https://unpkg.com/[email protected]/prop-types.js"></script>
<script src="https://unpkg.com/[email protected]/index.js"></script>
<script src="https://unpkg.com/[email protected]/dist/react-input-autosize.js"></script>
<script src="https://unpkg.com/react-select-plus/dist/react-select-plus.js"></script>

<link rel="stylesheet" href="https://unpkg.com/react-select-plus/dist/react-select-plus.css">

Usage

React-Select generates a hidden text field containing the selected value, so you can submit it as part of a standard form. You can also listen for changes with the onChange event property.

Options should be provided as an Array of Objects, each with a value and label property for rendering and searching. You can use a disabled property to indicate whether the option is disabled or not.

The value property of each option should be either a string or a number.

When the value is changed, onChange(selectedValueOrValues) will fire. Note that (as of 1.0) you must handle the change and pass the updated value to the Select.

import React from 'react';
import Select from 'react-select-plus';

class App extends React.Component {
  state = {
    selectedOption: '',
  }
  handleChange = (selectedOption) => {
    this.setState({ selectedOption });
    console.log(`Selected: ${selectedOption.label}`);
  }
  render() {
  	const { selectedOption } = this.state;
  	const value = selectedOption && selectedOption.value;
  	
    return (
      <Select
        name="form-field-name"
        value={value}
        onChange={this.handleChange}
        options={[
          { value: 'one', label: 'One' },
          { value: 'two', label: 'Two' },
        ]}
      />
    );
  }
}

You can customise the valueKey and labelKey props to use a different option shape.

Option Groups

You can generate option groups by structuring your options in a nested way as follows:

const options = [
	{
		label: 'Primary Colors', options: [
			{ label: 'Yellow', value: 'yellow' },
			{ label: 'Red', value: 'red' },
			{ label: 'Blue', value: 'blue' }
		]
	},
	{
		label: 'Secondary Colors', options: [
			{ label: 'Orange', value: 'orange' },
			{
				label: 'Purple', options: [
					{ label: 'Light Purple', value: 'light_purple' },
					{ label: 'Medium Purple', value: 'medium_purple' },
					{ label: 'Dark Purple', value: 'dark_purple' }
				]
			},
			{ label: 'Green', value: 'green' }
		]
	},
	{
		label: 'White',
		value: 'white',
	}
];

Custom classNames

You can provide a custom className prop to the <Select> component, which will be added to the base .Select className for the outer container.

The built-in Options renderer also support custom classNames, just add a className property to objects in the options array.

Multiselect options

You can enable multi-value selection by setting multi={true}. In this mode:

  • Selected options will be removed from the dropdown menu by default. If you want them to remain in the list, set removeSelected={false}
  • The selected values are submitted in multiple <input type="hidden"> fields, use the joinValues prop to submit joined values in a single field instead
  • The values of the selected items are joined using the delimiter prop to create the input value when joinValues is true
  • A simple value, if provided, will be split using the delimiter prop
  • The onChange event provides an array of selected options or a comma-separated string of values (eg "1,2,3") if simpleValue is true
  • By default, only options in the options array can be selected. Use the Creatable Component (which wraps Select) to allow new options to be created if they do not already exist. Hitting comma (','), ENTER or TAB will add a new option. Versions 0.9.x and below provided a boolean attribute on the Select Component (allowCreate) to achieve the same functionality. It is no longer available starting with version 1.0.0.
  • By default, selected options can be cleared. To disable the possibility of clearing a particular option, add clearableValue: false to that option:
var options = [
  { value: 'one', label: 'One' },
  { value: 'two', label: 'Two', clearableValue: false }
];

Note: the clearable prop of the Select component should also be set to false to prevent allowing clearing all fields at once

Accessibility Note

Selected values aren't focus targets, which means keyboard users can't tab to them, and are restricted to removing them using backspace in order. This isn't ideal and I'm looking at other options for the future; in the meantime if you want to use a custom valueComponent that implements tabIndex and keyboard event handling, see #2098 for an example.

Async options

If you want to load options asynchronously, use the Async export and provide a loadOptions Function.

The function takes two arguments String input, Function callbackand will be called when the input text is changed.

When your async process finishes getting the options, pass them to callback(err, data) in a Object { options: [] }.

The select control will intelligently cache options for input strings that have already been fetched. The cached result set will be filtered as more specific searches are input, so if your async process would only return a smaller set of results for a more specific query, also pass complete: true in the callback object. Caching can be disabled by setting cache to false (Note that complete: true will then have no effect).

Unless you specify the property autoload={false} the control will automatically load the default set of options (i.e. for input: '') when it is mounted.

import { Async } from 'react-select-plus';

const getOptions = (input, callback) => {
  setTimeout(() => {
    callback(null, {
      options: [
        { value: 'one', label: 'One' },
        { value: 'two', label: 'Two' }
      ],
      // CAREFUL! Only set this to true when there are no more options,
      // or more specific queries will not be sent to the server.
      complete: true
    });
  }, 500);
};

<Async
    name="form-field-name"
    loadOptions={getOptions}
/>

Note about filtering async options

The Async component doesn't change the default behaviour for filtering the options based on user input, but if you're already filtering the options server-side you may want to customise or disable this feature (see filtering options below)

Async options with Promises

loadOptions supports Promises, which can be used in very much the same way as callbacks.

Everything that applies to loadOptions with callbacks still applies to the Promises approach (e.g. caching, autoload, ...)

An example using the fetch API and ES6 syntax, with an API that returns an object like:

import { Async } from 'react-select-plus';

/*
 * assuming the API returns something like this:
 *   const json = [
 *      { value: 'one', label: 'One' },
 *      { value: 'two', label: 'Two' }
 *   ]
 */

const getOptions = (input) => {
  return fetch(`/users/${input}.json`)
    .then((response) => {
      return response.json();
    }).then((json) => {
      return { options: json };
    });
}

<Async
  name="form-field-name"
  value="one"
  loadOptions={getOptions}
/>

Async options loaded externally

If you want to load options asynchronously externally from the Select component, you can have the Select component show a loading spinner by passing in the isLoading prop set to true.

import Select from 'react-select-plus';

let isLoadingExternally = true;

<Select
  name="form-field-name"
  isLoading={isLoadingExternally}
  ...
/>

User-created tags

The Creatable component enables users to create new tags within react-select. It decorates a Select and so it supports all of the default properties (eg single/multi mode, filtering, etc) in addition to a couple of custom ones (shown below). The easiest way to use it is like so:

import { Creatable } from 'react-select-plus';

function render (selectProps) {
  return <Creatable {...selectProps} />;
};

Combining Async and Creatable

Use the AsyncCreatable HOC if you want both async and creatable functionality. It ties Async and Creatable components together and supports a union of their properties (listed above). Use it as follows:

import { AsyncCreatable } from 'react-select-plus';

function render (props) {
  // props can be a mix of Async, Creatable, and Select properties
  return (
    <AsyncCreatable {...props} />
  );
}

Filtering options

You can control how options are filtered with the following props:

  • matchPos: "start" or "any": whether to match the text entered at the start or any position in the option value
  • matchProp: "label", "value" or "any": whether to match the value, label or both values of each option when filtering
  • ignoreCase: Boolean: whether to ignore case or match the text exactly when filtering
  • ignoreAccents: Boolean: whether to ignore accents on characters like ø or å

matchProp and matchPos both default to "any". ignoreCase defaults to true. ignoreAccents defaults to true.

Advanced filters

You can also completely replace the method used to filter either a single option, or the entire options array (allowing custom sort mechanisms, etc.)

  • filterOption: function(Object option, String filter) returns Boolean. Will override matchPos, matchProp, ignoreCase and ignoreAccents options.
  • filterOptions: function(Array options, String filter, Array currentValues) returns Array filteredOptions. Will override filterOption, matchPos, matchProp, ignoreCase and ignoreAccents options.

For multi-select inputs, when providing a custom filterOptions method, remember to exclude current values from the returned array of options.

Filtering large lists

The default filterOptions method scans the options array for matches each time the filter text changes. This works well but can get slow as the options array grows to several hundred objects. For larger options lists a custom filter function like react-select-fast-filter-options will produce better results.

Efficiently rendering large lists with windowing

The menuRenderer property can be used to override the default drop-down list of options. This should be done when the list is large (hundreds or thousands of items) for faster rendering. Windowing libraries like react-virtualized can then be used to more efficiently render the drop-down menu like so. The easiest way to do this is with the react-virtualized-select HOC. This component decorates a Select and uses the react-virtualized VirtualScroll component to render options. Demo and documentation for this component are available here.

You can also specify your own custom renderer. The custom menuRenderer property accepts the following named parameters:

Parameter Type Description
focusedOption Object The currently focused option; should be visible in the menu by default.
focusOption Function Callback to focus a new option; receives the option as a parameter.
labelKey String Option labels are accessible with this string key.
optionClassName String The className that gets used for options
optionComponent ReactClass The react component that gets used for rendering an option
optionRenderer Function The function that gets used to render the content of an option
options Array<Object> Ordered array of options to render.
selectValue Function Callback to select a new option; receives the option as a parameter.
valueArray Array<Object> Array of currently selected options.

Updating input values with onInputChange

You can manipulate the input by providing a onInputChange callback that returns a new value. Please note: When you want to use onInputChange only to listen to the input updates, you still have to return the unchanged value!

function cleanInput(inputValue) {
    // Strip all non-number characters from the input
    return inputValue.replace(/[^0-9]/g, "");
}

<Select
    name="form-field-name"
    onInputChange={cleanInput}
/>

Overriding default key-down behaviour with onInputKeyDown

Select listens to keyDown events to select items, navigate drop-down list via arrow keys, etc. You can extend or override this behaviour by providing a onInputKeyDown callback.

function onInputKeyDown(event) {
    switch (event.keyCode) {
        case 9:   // TAB
            // Extend default TAB behaviour by doing something here
            break;
        case 13: // ENTER
            // Override default ENTER behaviour by doing stuff here and then preventing default
            event.preventDefault();
            break;
    }
}

<Select
    {...otherProps}
    onInputKeyDown={onInputKeyDown}
/>

loadOptions function undefined function that returns a promise or calls a callback with the options: function(input, [callback])

Creatable properties

Property Type Description
children function Child function responsible for creating the inner Select component. This component can be used to compose HOCs (eg Creatable and Async). Expected signature: (props: Object): PropTypes.element
isOptionUnique function Searches for any matching option within the set of options. This function prevents duplicate options from being created. By default this is a basic, case-sensitive comparison of label and value. Expected signature: ({ option: Object, options: Array, labelKey: string, valueKey: string }): boolean
isValidNewOption function Determines if the current input text represents a valid option. By default any non-empty string will be considered valid. Expected signature: ({ label: string }): boolean
newOptionCreator function Factory to create new option. Expected signature: ({ label: string, labelKey: string, valueKey: string }): Object
onNewOptionClick function new option click handler, it calls when new option has been selected. function(option) {}
shouldKeyDownEventCreateNewOption function Decides if a keyDown event (eg its keyCode) should result in the creation of a new option. ENTER, TAB and comma keys create new options by default. Expected signature: ({ keyCode: number }): boolean
promptTextCreator function Factory for overriding default option creator prompt label. By default it will read 'Create option "{label}"'. Expected signature: (label: String): String

Methods

Use the focus() method to give the control focus. All other methods on <Select> elements should be considered private.

// focuses the input element
<instance>.focus();
