Selectable items for React
Allows individual or group selection of items using the mouse.
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 selectiononNonItemClick
(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 todiv
.fixedPosition
(Boolean) Whether the<SelectableGroup />
container is a fixed/absolute position element or the grandchild of one. Note: if you get an error thatValue 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 theonSelection
callback while the mouse is moving. Throttled to 50ms for performance in IE/EdgepreventDefault
(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:
- run
npm i --save-dev babel-plugin-transform-decorators-legacy
- Add the following line to your
.babelrc
:
{
"plugins": ["transform-decorators-legacy"]
}
