//Initialize ListView control
let listviewObject: ListView = new ListView({
    //set the data to datasource property
    dataSource: continent,
    // map the  fields 
    fields: { tooltip: 'text' , groupBy:'category',text:'text',id:'id'},
    headerTitle: 'Continent',
    showHeader: true,
    animation : {effect: 'Zoom', duration: 300, easing: 'ease'  }
});

//Render initialized ListView
listviewObject.appendTo("#list");

checkBoxPosition

checkBoxPosition

The checkBoxPosition is used to set the position of check box in a list item. By default, the checkBoxPosition is Left, which will appear before the text content in a list item.

     <div id='list'></div>
  import {ListView} from '@syncfusion/ej2-lists';
  let arts: string[] = ["Artwork", "Abstract", "Modern Painting", "Ceramics", "Animation Art", "Oil Painting"];

//Initialize ListView control
let listviewObject: ListView = new ListView({
    //set the data to datasource property
    dataSource: arts,
    showCheckBox:true,
    checkBoxPosition: "Right"
});

//Render initialized ListView
listviewObject.appendTo("#list");

cssClass

string

The cssClass property is used to add a user-preferred class name in the root element of the ListView, using which we can customize the component (both CSS and functionality customization)

     <div id='list'></div>
     <style>
      .custom
       {
        font-style: italic;
       }
    </style>
  import {ListView} from '@syncfusion/ej2-lists';
  let arts: string[] = ["Artwork", "Abstract", "Modern Painting", "Ceramics", "Animation Art", "Oil Painting"];

//Initialize ListView control
let listviewObject: ListView = new ListView({
    //set the data to datasource property
    dataSource: arts,
    cssClass: "custom"
});

//Render initialized ListView
listviewObject.appendTo("#list");

dataSource

Object[] | string[] | number[] | DataManager

The dataSource provides the data to render the ListView component which is mapped with the fields of ListView.

enable

boolean

If enable set to true, the list items are enabled. And, we can disable the component using this property by setting its value as false.

     <div id='list'></div>
  import {ListView} from '@syncfusion/ej2-lists';
  let arts: string[] = ["Artwork", "Abstract", "Modern Painting", "Ceramics", "Animation Art", "Oil Painting"];

//Initialize ListView control
let listviewObject: ListView = new ListView({
    //set the data to datasource property
    dataSource: arts,
    enable: false
});

//Render initialized ListView
listviewObject.appendTo("#list");

enableHtmlSanitizer

boolean

If enableHtmlSanitizer set to true, allows the cross-scripting site.

     <div id='list'></div>
  import {ListView} from '@syncfusion/ej2-lists';
  let arts: string[] = ["Artwork", "Abstract", "Modern Painting", "Ceramics", "Animation Art", "Oil Painting"];

//Initialize ListView control
let listviewObject: ListView = new ListView({

    enableHtmlSanitizer: true
});

//Render initialized ListView
listviewObject.appendTo("#list");

enablePersistence

boolean

enableRtl

boolean

Enable or disable rendering component in right to left direction.

enableVirtualization

boolean

If enableVirtualization set to true, which will increase the ListView performance, while loading a large amount of data.

     <div id='list'></div>
import { ListView, Virtualization } from '@syncfusion/ej2-lists';

ListView.Inject(Virtualization);/*Inject Virtualization*/

let listData: { [key: string]: string | object }[] = [];

listData = [
    { text: 'Nancy', id: '0', },
    { text: 'Andrew', id: '1' },
    { text: 'Janet', id: '2' },
    { text: 'Margaret', id: '3' },

    { text: 'Michael', id: '7' },
    { text: 'Albert', id: '8' },
    { text: 'Nolan', id: '9' }
];

for (let i: number = 10; i <= 1010; i++) {
    let index: number = parseInt((Math.random() * 10).toString());
    listData.push({ text: listData[index].text, id: i.toString() });
}

let listviewObject: ListView = new ListView({

    //Set defined data to dataSource property.
    dataSource: listData,
    //Set height
    height: 500,
    //enable UI virtualization
    enableVirtualization: true,
});
    //Render initialized ListView component
    listviewObject.appendTo('#list');
