React List

A React version of an MDC List.

Installation

``
npm install @material/react-list
`

Usage

$3

with Sass:
`js
import '@material/react-list/index.scss';
`

with CSS:
`js
import '@material/react-list/dist/list.css';
`

$3

`js
import React, {Component} from 'react';
import List, {ListItem, ListItemText} from '@material/react-list';

class MyApp extends Component {
render() {
return (











);
}
}
`

> _NOTE_: Please use the ListItem component to specify list items. List will not recognize custom list item components.
>
> Also, you can override the element that the List or ListItem renders by passing in a tag prop. By default, List renders a ul and ListItem renders an li. For semantic HTML and a11y, as well as working with routing libraries such as React Router and Next.js' Link, you may wish to use nav and a respectively if using the components to render a page's navigation.

Variants

$3

You can use the twoLine Boolean prop for List combined with the secondaryText prop for ListItem to style a list as a double line list.

`js
import React, {Component} from 'react';
import List, {ListItem, ListItemText} from '@material/react-list';

class MyApp extends Component {
render() {
return (


primaryText='Photos'
secondaryText='Jan 9, 2018' />


primaryText='Recipes'
secondaryText='Jan 17, 2018' />


primaryText='Work'
secondaryText='Jan 28, 2018' />


);
}
}
`

$3

You may add a leading visuals or trailing metadata to a list item using ListItemGraphic before or ListItemMeta after ListItemText.

`js
import React, {Component} from 'react';
import MaterialIcon from '@material/react-material-icon';
import List, {ListItem, ListItemGraphic, ListItemText, ListItemMeta} from '@material/react-list';

class MyApp extends Component {
render() {
return (


} />



...

);
}
}

`

$3

Multiple related lists can be grouped together using the ListGroup component. Optional subheaders can be added using ListGroupSubheader. ListDividers can be used to separate content either within a list or between lists.

`js
import React, {Component} from 'react';
import List, {
ListItem, ListItemText, ListGroup,
ListGroupSubheader,ListDivider
} from '@material/react-list';

class MyApp extends Component {
render() {
return (

Folders




...


Recent Files




...


);
}
}
`

$3

You can use the singleSelection Boolean prop for List to allow for selection of list items. You can also set the selectedIndex of the list programmatically and include a handleSelect callback.

> _NOTE_: If you are inserting or removing list items, you must update the selectedIndex accordingly.

`js
import React, {Component} from 'react';
import List, {ListItem, ListItemText} from '@material/react-list';

class MyApp extends Component {
state = {
selectedIndex: 1,
};

render() {
return (
singleSelection
selectedIndex={this.state.selectedIndex}
handleSelect={(selectedIndex) => this.setState({selectedIndex})}
>










);
}
}
`

$3

You can use the checkboxList Boolean prop for List to enable the checkbox list logic. You must also set selectedIndex of the list to an array. selectedIndex will be an empty array if there is no initial selection. Setting selectedIndex will initialize the list with the correct tabIndex. Changing this programatically will not affect the checkboxes -- you must programatically change the checkbox via it's checked prop and update selectedIndex to keep a11y up to date. See the Checkbox Readme for more details.

`jsx
import React, {Component} from 'react';
import List, {ListItem, ListItemText} from '@material/react-list';
import Checkbox from '@material/react-checkbox';

class MyApp extends Component {
state = {
selectedIndex: [1],
};

render() {
return (
checkboxList
selectedIndex={this.state.selectedIndex}
handleSelect={(activatedIndex, allSelected) => this.setState({selectedIndex: allSelected})}
>













);
}
}
`

$3

You can use the radioList Boolean prop for List to enable the radio list logic. Set selectedIndex to the index of the listItem initially selected to accurately setup the component for a11y. Changing selectedIndex programatically will not affect the radio element -- you must instead programatically change the radio via it's checked prop. Interactions (click/arrow keys) will update the radios as expected. To get the selectedIndex, setup the radio's onChange method as shown below. See the Radio Readme for more details.

> Note: We know this API is inconsistent with checkbox list. This is because the implementations of radio and checkbox differ. In the coming months, we will try to normalize the design.

`jsx
import React, {Component} from 'react';
import List, {ListItem, ListItemText} from '@material/react-list';
import Radio, {NativeRadioControl} from '@material/react-radio';

class MyApp extends Component {
state = {
selectedItem: 'Milk',
};

handleChange = (e) => {
this.setState({selectedItem: e.target.value});
}

render() {
const listItems = ['Photos', 'Recipes', 'Work'];

return (
radioList
selectedIndex={0}
>
{
listItems.map((item, index) => {
return (


name={item}
checked={this.state.selectedItem === item}
value={item}
id={${index}-${item}}
onChange={this.handleChange}
/>



);
})
}

);
}
}
`
