react-bootstrap-combobox

A combo-box component for React Bootstrap.

Project Home | API Docs

This is a very simple stateless wrapper around DropdownButton and MenuItem.

Features

1. Minimizes the number of characters one would need to type when building a component in this fashion
2. Provides a good looking dropdown component, built on Twitter Bootstrap, customizable with SASS, that works and looks the same in all major browsers
3. The dropdown menu has a maximum height automatically calculated to prevent it from overflowing the viewport
4. Provides a number of performance optimizations, both in JavaScript and CSS

Hint

Do not forget to set the NODE_ENV environment variable to "production" in production to get some instant performance increase from React for free!

Installation

npm i react-bootstrap-combobox --save

Usage

You need to include the "_index.scss" file from this package. If you are using webcompiler then you can simply do:

// import Bootstrap
@import "bootstrap";
// import Bootstrap theme
@import "bootstrap/theme";
// import the component
@import "react-bootstrap-combobox";

and then:

import {Combo} from 'react-bootstrap-combobox';
 
function someFunc(key: string) {
  ...
}
 
<Combo items={{
  // keys must be unique
  sweden: {label: 'Sweden', header: true}, // any combination of props supported by MenuItem
  volvo: 'Volvo',                          // same as {label: 'Volvo'}
  saab: 'Saab',
  separator: '-',                          // same as {divider: true}
  germany: {label: 'Germany', header: true},
  mercedes: 'Mercedes',
  audi: 'Audi'
}} value="volvo" onChange={someFunc} />

Caveats

1. Both items and value are required props
2. The component is stateless, which means that its value cannot be changed without re-rendering it
3. For performance reasons items are considered immutable
