Customizing templates in EJ2 JavaScript Listview control

8 May 202319 minutes to read

The ListView control is designed to customize list items, group title and header title. It uses Essential JS2 Template engine to render the elements.

Header template

ListView header can be customized with the help of the headerTemplate property.

To customize header template in your application, set your customized template string to headerTemplate property along with showHeader property as true to display the ListView header.

let listviewInstance: ListView = new ListView({
     data: listData,
     headerTemplate: '<div class="header-content"><span>Header</span></div>',
     showHeader: true
})

In the following example, we have rendered Listview with customized header which contains search, add and sort buttons.

var fruitsdata = [
    { text: 'Date', id: '1', imgUrl: './dates.jpg' },
    { text: 'Fig', id: '2', imgUrl: './fig.jpg' },
    { text: 'Apple', id: '3', imgUrl: './apple.png' },
    { text: 'Apricot', id: '4', imgUrl: './apricot.jpg' },
    { text: 'Grape', id: '5', imgUrl: './grape.jpg' },
    { text: 'Strawberry', id: '6', imgUrl: './strawberry.jpg' },
    { text: 'Pineapple', id: '7', imgUrl: './pineapple.jpg' },
    { text: 'Melon', id: '8', imgUrl: './melon.jpg' },
    { text: 'Lemon', id: '9', imgUrl: './lemon.jpg' },
    { text: 'Cherry', id: '10', imgUrl: './cherry.jpg' },
];

var listViewInstance = new ej.lists.ListView({
    dataSource: fruitsdata,
    headerTemplate: '<div class="headerContainer"><span class="fruitHeader">Fruits</span><button id="search"></button><button id="add"></button><button id="sort"></button></div>',
    showHeader: true,
    actionComplete: renderHeaderButtons
});

listViewInstance.appendTo('#element');

function renderHeaderButtons() {
    ['search', 'sort', 'add'].forEach((item) => {
        new ej.buttons.Button({ iconCss: `e-icons e-${item}-icon`, cssClass: 'e-small e-round', isPrimary: true }, `#${item}`)
    });
}

Template

ListView items can be customized with the help of the template property.

To customize list items in your application, set your customized template string to template property.

let listviewInstance: ListView = new ListView({
     data: listData,
     template: '<div class="list-tem"><span>${text}</span></div>',
})

We provided the following built-in CSS classes to customize the list-items. Refer to the following table.

CSS class Description
e-list-template, e-list-wrapper These classes are used to differentiate normal and template rendering, which are mandatory for template rendering. The e-list-template class should be added to the root of the ListView element and e-list-wrapper class should be added to the template element wrapper

new ListView({
dataSource: data,
cssClass: 'e-list-template',
template: '<div class="e-list-wrapper"></div>'}, '#list');
e-list-content This class is used to align list content and it should be added to the content element

<div class="e-list-wrapper">
<span class="e-list-content">ListItem</span>
</div>
e-list-avatar This class is used for avatar customization. It should be added to the template element wrapper. After adding it, we can customize our element with Avatar classes

<div class="e-list-wrappere-list-avatar">
<span class="e-avatar e-avatar-circle">MR</span>
<span class="e-list-content">ListItem</span>
</div>
e-list-avatar-right This class is used to align avatar to right side of the list item. It should be added to the template element wrapper. After adding it, we can customize our element with Avatar classes

<div class="e-list-wrappere-list-avatar-right">
<span class="e-list-content">ListItem</span>
<span class="e-avatar e-avatar-circle">MR</span>
</div>
e-list-badge This class is used for badge customization .It should be added to the template element wrapper. After adding it, we can customize our element with Badge classes

<div class="e-list-wrappere-list-badge">
<span class="e-list-content">ListItem</span>
<span class="e-badge e-badge-primary">MR</span>
</div>
e-list-multi-line This class is used for multi-line customization. It should be added to the template element wrapper. After adding it, we can customize List item’s header and description

<div class="e-list-wrappere-list-multi-line">
<span class="e-list-content">ListItem</span>
</div>
e-list-item-header This class is used to align a list header and it should be added to the header element along with the multi-line class

<div class="e-list-wrappere-list-multi-line">
<span class="e-list-item-header">ListItem Header</span>
<span class="e-list-content">ListItem</span>
</div>

In the following example, we have customized list items with built-in CSS classes.

var template = '<div class="e-list-wrapper e-list-multi-line e-list-avatar">' +
    '${if(avatar!=="")}' +
    '<span class="e-avatar e-avatar-circle">${avatar}</span>' +
    '${else}' +
    '<span class="${pic} e-avatar e-avatar-circle"> </span>' +
    '${/if}' +
    '<span class="e-list-item-header">${text}</span>' +
    '<span class="e-list-content">${contact}</span>' +
    '</div>';

    //Define an array of JSON data
    var dataSource = [
        {
            text: "Jenifer",
            contact: "(206) 555-985774",

            avatar: "",
            pic: "pic02"
        },
        {

            contact: "(71) 555-5598",
            id: "8",
            avatar: "",
            pic: "pic03"
        },
        {
            text: "Charlotte",
            contact: "(206) 555-1189",
            id: "9",
            avatar: "C",
            pic: ""
        }
    ];
    // Initialize ListView component
    var listObj = new ej.lists.ListView({
        //Set defined data to dataSource property
        dataSource: dataSource,
        //Map the appropriate columns to fields property
        fields: { text: "text" },
        cssClass: 'e-list-template',
        //set width of ListView
        width: "350px",
        //enable ListView header
        showHeader: true,
        //set header title
        headerTitle: "Contacts",
        //Set customized template
        template: template,
        sortOrder: "Ascending"
    });
    //Render initialized ListView component
    listObj.appendTo("#List");

<body>
    
    <div id="container">
    <div id="List" tabindex="1"></div>
    </div>

<script>
var ele = document.getElementById('container');

Group template

ListView group header can be customized with the help of the groupTemplate property.

To customize the group template in your application, set your customized template string to groupTemplate property.

let listviewInstance: ListView = new ListView({
     data: listData,
     groupTemplate: '<div class="group-header"><span>${items[0].category}</span></div>',
})

In the following example, we have grouped Listview based on the category. The category of each list item should be mapped with groupBy field of the data. We have also displayed grouped list items count in the group list header.

var template = '<div class="e-list-wrapper e-list-multi-line e-list-avatar">' +
    '<img class="e-avatar e-avatar-circle" src=${image} style="background:#BCBCBC" />' +
    '<span class="e-list-item-header">${Name}</span>' +
    '<span class="e-list-content">${contact}</span>' +
    '</div>';

    //Define an array of JSON data
    var dataSource = [
        { Name: 'Nancy', contact:'(206) 555-985774', id: '1', image: 'https://ej2.syncfusion.com/demos/src/grid/images/1.png',  category: 'Experience'},

    ];

    // Initialize ListView component
    var listObj = new ej.lists.ListView({

        //Set defined data to dataSource property
        dataSource: dataSource,

        width: 350,

        //Map the appropriate columns to fields property
        fields: { text: 'Name', groupBy: 'category' },
        cssClass: 'e-list-template',
        //Set customized template
        template: template,
        groupTemplate: '<div><span class="category">${items[0].category}</span> <span class="count"> ${items.length} Item(s)</span></div> '

    });

    //Render initialized ListView component
    listObj.appendTo('#List');

<body>
    
    <div id="container">
        <div class="col-lg-12 control-section">

            <!-- ListView element -->
            <div id="List" tabindex="1">
            </div>
        </div>

<script>
var ele = document.getElementById('container');
if(ele) {
  ele.style.visibility = "visible";
}   
      </script>
<script src="index.js" type="text/javascript"></script>
</body></html>

We can also render other EJ2 controls in ListView templates by rendering that controls on actionComplete event. Refer to the below code snippet.

let listviewInstance: ListView = new ListView({
     data: listData,
     template: '<div><span>${text}</span><button id="delete"></button></div>',
     actionComplete: () => {
         new Button({iconCss: 'e-icons e-delete-icon' cssClass: 'e-small e-round', isPrimary: true }, '#delete')
     }
})
