React-selectable-fast

Enable a React component (or group of components) to be selectable via mouse/touch.

Install

npm i -S @seonghyenkimm/react-selectable-fast

# with yarn
yarn add @seonghyeonkimm/react-selectable-fast

Based on react-selectable-fast

This project is forked from react-selectable-fast by valerybugakov. The reason why I forked this package is because I wanted to update package and to keep on manage package.

Usage

Package exports 5 entities

export { TSelectableItemProps, SelectableGroup, createSelectable, SelectAll, DeselectAll }

To make other components selectable wrap them using HoC createSelectable, add passed selectableRef prop to the target node and put a list of seletable items under SelectableGroup.

import React, { Component } from 'react'
import { SelectableGroup } from 'react-selectable-fast'

class App extends Component {
  ...

  render() {
    return (
      <SelectableGroup
        className="main"
        clickClassName="tick"
        enableDeselect
        tolerance={this.state.tolerance}
        globalMouse={this.state.isGlobal}
        allowClickWithoutSelected={false}
        duringSelection={this.handleSelecting}
        onSelectionClear={this.handleSelectionClear}
        onSelectionFinish={this.handleSelectionFinish}
        onSelectedItemUnmount={this.handleSelectedItemUnmount}
        ignoreList={['.not-selectable', '.item:nth-child(10)', '.item:nth-child(27)']}
      >
        <List items={this.props.items} />
      </SelectableGroup>
    )
  }
}

import React from 'react'
import { TSelectableItemProps, createSelectable } from 'react-selectable-fast'

class SomeComponent extends Component<TSelectableItemProps> {
  render() {
    const { selectableRef, isSelected, isSelecting } = this.props

    return <div ref={selectableRef}>...</div>
  }
}

export default createSelectable(SomeComponent)

import React from 'react'
import { SelectAll, DeselectAll } from 'react-selectable-fast'
import SelectableComponent from './SomeComponent'

const List = () => (
  <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} player={item.player} year={item.year} />
    ))}
  </div>
)

JavaScript environment requirements

The React-Selectable-Fast package distributed on NPM use the widely-supported ES5 version of JavaScript to support as many browser environments as possible.

However, this package expects modern JavaScript globals (Map, Set, Array.from, Array.isArray Object.assign) to be defined. If you support older browsers and devices which may not yet provide these natively, consider including a global polyfill in your bundled application, such as core-js or babel-polyfill.

A polyfilled environment for React-Selectable-Fast using core-js to support older browsers might look like this:

import 'core-js/fn/object/assign'
import 'core-js/fn/array/from'
import 'core-js/fn/array/is-array'
import 'core-js/fn/map'
import 'core-js/fn/set'

import App from './myApp'

Configuration

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

• duringSelection (Function) Callback fired rapidly during selection (while the selector is being dragged). Passes an array containing selectable items currently under the selector to the callback function.
• onSelectionFinish (Function) Callback.
• onSelectionClear (Function) Callback.
• onSelectedItemUnmount (Function) Callback.
• enableDeselect (Boolean) Enables deselect with selectbox.
• mixedDeselect (Boolean) When enabled items can be selected and deselected with selectbox at the same time, enableDeselect should be set to true.
• scrollContainer (String) Selector of scroll container which will be used to calculate selectbox position. If not specified SelectableGroup element will be used as scroll container.
• ignoreList (Array) Array of ignored selectors.
• clickClassName (String) On elements with specified selector click item containing this element will be selected.
• tolerance (Number) The amount of buffer to add around your <SelectableGroup /> container, in pixels.
• className (String) Class of selectable group element.
• selectionModeClass (String) Class indicating that there is more than 1 selected item. Defaults to 'in-selection-mode'.
• selectboxClassName (String) Class of selectbox element. (default: selectable-selectbox)
• component (String) The component to render. Defaults to div.
• allowClickWithoutSelected (Boolean) When disabled items can be selected by click only if there is more than 1 already selected item.
• fixedPosition (Boolean) Whether the <SelectableGroup /> container is a fixed or absolutely positioned element or the grandchild of one.
• resetOnStart (Boolean) Unselect all items when you start a new drag. Default value is false.
• deselectOnEsc (Boolean) Unselect all items on ESC keydown/keyup events. Default value is true. Using ref on SelectableGroup gives access to ref.clearSelection() method to unselect all items programmatically.
• disabled (Boolean) Enable or disable the selectable draggable, useful if you want to enable drag of sub-items. Default value is false.
• delta (Number) Value of the CSS transform property scaled list, useful if your list of items in <SelectableGroup /> is wrapped by a scale css transform property. Default value is 1.
• selectOnClick (Boolean) Allow selecting by clicking items. Default value is true
• allowAltClick (Boolean) Perform select actions even though the alt key is down when clicking or dragging. Default value is false
• allowCtrlClick (Boolean) Perform select actions even though the ctrl key is down when clicking or dragging. Default value is false
• allowMetaClick (Boolean) Perform select actions even though the meta key is down when clicking or dragging. Default value is false
• allowShiftClick (Boolean) Perform select actions even though the shift key is down when clicking or dragging. Default value is false
