Based on react-selectable
This project is based on react-selectable by unclecheese.
Main idea of this fork is to eliminate render during selection caused by state updates of SelectableGroup. Only items under selectbox rerender themself, which great for big lists of selectable items. Also this package extends the original functionality with ability to scroll items while selecting relative to window and specified scroll container.
Getting started
npm install react-selectable-fast
Package exports 4 entities { SelectableGroup, createSelectable, SelectAll, DeselectAll }
.
To make other components selectable create selectable component with createSelectable
function and put list of them under SelectableGroup
.
import React, { Component, PropTypes } from 'react'
import { SelectableGroup } from 'react-selectable-fast'
class App extends Component {
...
render() {
return (
<SelectableGroup
className="main"
clickableClassName="tick"
onSelectionStart={this.handleSelectionStart}
duringSelection={this.handleSelecting}
onSelectionFinish={this.handleSelectionFinish}
onSelectionClear={this.handleSelectionClear}
globalMouse={this.state.isGlobal}
tolerance={this.state.tolerance}
distance={this.state.distance}
whiteList={['.not-selectable']}
allowClickWithoutSelected={false}
dontClearSelection
>
<List items={this.props.items} />
</SelectableGroup>
)
}
}
import React, { Component, PropTypes } from 'react'
import { createSelectable, SelectAll, DeselectAll } from 'react-selectable-fast'
import SomeComponent from './SomeComponent'
const SelectableComponent = createSelectable(SomeComponent)
class List extends Component {
...
render() {
return (
<div>
<SelectAll className="selectable-button">
<button>Select all</button>
</SelectAll>
<DeselectAll className="selectable-button">
<button>Clear selection</button>
</DeselectAll>
{this.props.items.map((item, i) => (
<SelectableComponent
key={i}
title={item.title}
year={item.year}
/>
))}
</div>
)
}
}

(Array) Array of whitelisted selectors.clickableClassName
(String) On element with specified selector click item cotaining this element will be selected.tolerance
(Number) The amount of buffer to add around your <SelectableGroup />
