Customize Item Appearance

For a minor customization of List items, you can use the default item template. This template defines the appearance of an item depending on whether specific fields are present or absent from the item's data object. For example, the following code generates three items: each item has a badge, the second is disabled and the third is hidden.

jQuery
JavaScript
var fruits = [
    { text: "Apples", badge: 10 },
    { text: "Oranges", badge: 12, disabled: true },
    { text: "Lemons", badge: 15, visible: false }
];

$(function() {
    $("#listContainer").dxList({
        dataSource: fruits
    });
});
Angular
TypeScript
HTML
import { DxListModule } from 'devextreme-angular';
// ...
export class AppComponent {
    fruits = [
        { text: "Apples", badge: 10 },
        { text: "Oranges", badge: 12, disabled: true },
        { text: "Lemons", badge: 15, visible: false }
    ];
}
@NgModule({
    imports: [
        // ...
        DxListModule
    ],
    // ...
})
<dx-list
    [dataSource]="fruits">
</dx-list>

Using the default item template is the easiest way to customize an item, but it lacks flexibility. Instead, you can define a custom template for widget items. For Angular, AngularJS, and Knockout apps, DevExtreme provides a markup component called dxTemplate. The following code shows how you can use dxTemplate to define a template for List items.

Angular
HTML
TypeScript
<dx-list
    [dataSource]="fruits"
    itemTemplate="listItem">
    <div *dxTemplate="let item of 'listItem'">
        <b>{{item.name}}</b><br />
        <p style="margin:0px">{{item.count}}</p>
    </div>
</dx-list>
import { DxListModule } from 'devextreme-angular';
// ...
export class AppComponent {
    fruits = [
        { name: "Apples", count: 10 },
        { name: "Oranges", count: 12 },
        { name: "Lemons", count: 15 },
        { name: "Pears", count: 20 },
        { name: "Pineapples", count: 3 }
    ];
}
@NgModule({
    imports: [
        // ...
        DxListModule
    ],
    // ...
})
AngularJS
HTML
JavaScript
<div ng-controller="DemoController">
    <div dx-list="{
        dataSource: fruits,
        itemTemplate: 'listItem'
    }" dx-item-alias="fruit">
        <div data-options="dxTemplate: { name: 'listItem' }">
            <b>{{ fruit.name }}</b><br />
            <p style="margin:0px">{{ fruit.count }}</p>
        </div>
    </div>
</div>
angular.module('DemoApp', ['dx'])
    .controller('DemoController', function ($scope) {
        $scope.fruits = [
            { name: "Apples", count: 10 },
            { name: "Oranges", count: 12 },
            { name: "Lemons", count: 15 },
            { name: "Pears", count: 20 },
            { name: "Pineapples", count: 3 }
        ];
    });
NOTE
The dx-item-alias directive specifies the variable that is used to access the item object.
Knockout
HTML
JavaScript
<div data-bind="dxList: {
    dataSource: fruits,
    itemTemplate: 'listItem'
}">
    <div data-options="dxTemplate: { name: 'listItem' }">
        <b data-bind="text: name"></b><br />
        <p data-bind="text: count" style="margin:0px"></p>
    </div>
</div>
var viewModel = {
    fruits: [
        { name: "Apples", count: 10 },
        { name: "Oranges", count: 12 },
        { name: "Lemons", count: 15 },
        { name: "Pears", count: 20 },
        { name: "Pineapples", count: 3 }
    ]
};

ko.applyBindings(viewModel);

If you use jQuery alone, combine the HTML markup for items manually with jQuery DOM manipulation methods. To apply this markup, use the itemTemplate callback function as shown in the following code.

JavaScript
var fruits = [
    { name: "Apples", count: 10 },
    { name: "Oranges", count: 12 },
    { name: "Lemons", count: 15 },
    { name: "Pears", count: 20 },
    { name: "Pineapples", count: 3 }
];

$(function() {
    $("#listContainer").dxList({
        dataSource: fruits,
        itemTemplate: function(data, _, element) {
            element.append(
                $("<b>").text(data.fruit), $("<br />"),
                $("<p>").text(data.count).css("margin", 0)
            )
        }
    });
});

You can also customize an individual List item. For this purpose, declare a template for this item as a script and pass its id to the template field.

HTML
JavaScript
<script id="individualTemplate" type="text/html">
    <!-- ... -->
</script>
var fruits = [
    { name: "Apples", count: 10 },
    { name: "Oranges", count: 12, template: $("#individualTemplate") },
    // ...
];

In addition, you can use a 3rd-party template engine to perform the needed customizations. For more information, see the Use an Alternative Template Engine article.
