Getting started

npm install react-selectable

import React from 'react';
import { render } from 'react-dom';
import { SelectableGroup, createSelectable } from 'react-selectable';
import SomeComponent from './some-component';

const SelectableComponent = createSelectable(SomeComponent);

class App extends React.Component {

  constructor (props) {
  	super(props);
  	this.state = {
  		selectedKeys: []
  	};
  }

  render () {
    return (
      <SelectableGroup onSelection={this.handleSelection}>
        {this.props.items.map((item, i) => {
          	let selected = this.state.selectedKeys.indexOf(item.id) > -1;
          	return (
          		<SelectableComponent key={i} selected={selected} selectableKey={item.id}>
          			{item.title}
          		</SelectableComponent>
          	);
        })}
      </SelectableGroup>
    );
  },

  handleSelection (selectedKeys) {
  	this.setState({ selectedKeys });
  }

}

Configuration

The <SelectableGroup /> component accepts a few optional props:

  • onSelection (Function) Callback fired after user completes selection
  • onNonItemClick (Function) Callback fired when a click happens within the selectable group component, but not in a selectable item. Useful for clearing selection.
  • tolerance (Number) The amount of buffer to add around your <SelectableGroup /> container, in pixels.
  • component (String) The component to render. Defaults to div.
  • fixedPosition (Boolean) Whether the <SelectableGroup /> container is a fixed/absolute position element or the grandchild of one. Note: if you get an error that Value must be omitted for boolean attributes when you try <SelectableGroup fixedPosition={true} />, simply use Javascript's boolean object function: <SelectableGroup fixedPosition={Boolean(true)} />.
  • selectOnMouseMove (Boolean) Enable to fire the onSelection callback while the mouse is moving. Throttled to 50ms for performance in IE/Edge
  • preventDefault (Boolean) Allows to enable/disable preventing the default action of the onmousedown event (with e.preventDefault). True by default. Disable if your app needs to capture this event for other functionalities.
  • enabled (Boolean) If false, all of the selectable features are disabled, and event handlers removed.

Decorators

Though they are optional, you can use decorators with this react-selectable.

A side by side comparison is the best way to illustrate the difference:

Without Decorators

class SomeComponent extends Component {

}
export default createSelectable(SomeComponent)

vs.

With Decorators

@createSelectable
export default class SomeComponent extends Component {

}

In order to enable this functionality, you will most likely need to install a plugin (depending on your build setup). For Babel, you will need to make sure you have installed and enabled babel-plugin-transform-decorators-legacy by doing the following:

  1. run npm i --save-dev babel-plugin-transform-decorators-legacy
  2. Add the following line to your .babelrc:
{
  "plugins": ["transform-decorators-legacy"]
}
