React

Templates are passed as properties that end with ...Render or ...Component. Each template has access to the following parameters:

  • data
    A data source object or an object with fields specific to a particular template. For information on the contents of data, refer to the Template Data section of the template's API reference article.

  • index
    A zero-based index of the item in the collection. Available only in collection UI component templates.

  • element
    A jQuery element that represents the UI component element being customized. Available only if you use jQuery.

The following code shows how to declare a template and use these parameters. This code declares an itemTemplate for the List UI component:

jQuery
index.js
$(function() {
    $("#listContainer").dxList({
        items: [
            { itemProperty: "someValue" },
            // ...
        ],
        itemTemplate: function (data, index, element) {
            return index + " - " + data.itemProperty;

            // ===== or using the "element" parameter =====
            const $item = $("<div>").text(
                index + " - " + data.itemProperty
            );
            element.append($item);
        }
    });
});
Angular
app.component.html
app.component.ts
app.module.ts
<dx-list
    [items]="listData"
    itemTemplate="list-item">
    <div *dxTemplate="let data of 'list-item'; let index = index">
        {{index}} - {{data.itemProperty}}
    </div>
</dx-list>
import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    listData = [
        { itemProperty: "someValue" },
        // ...
    ]
}
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { DxListModule } from 'devextreme-angular';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        DxListModule
    ],
    providers: [ ],
    bootstrap: [AppComponent]
})
export class AppModule { }
Vue
App.vue
<template>
    <DxList
        :items="listData"
        item-template="list-item">
        <template #list-item="{ data, index }">
            {{ index }} - {{ data.itemProperty }}
        </template>
    </DxList>
</template>

<script>
import 'devextreme/dist/css/dx.light.css';

import DxList from 'devextreme-vue/list';

export default {
    components: {
        DxList
    },
    data() {
        return {
            listData: [
                { itemProperty: 'someValue' },
                // ...
            ]
        }
    }
}
</script>
React
App.js
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import List from 'devextreme-react/list';

const renderListItem = (data, index) => {
    return (
        <div>{index} - {data.itemProperty}</div>
    );
}

class App extends React.Component {
    listData = [
        { itemProperty: 'someValue' },
        // ...
    ];

    render() {
        return (
            <List
                items={this.listData}
                itemRender={renderListItem}
            />
        );
    }
}
export default App;

Collection UI components also support templates for individual items. Do not specify the UI component's dataSource property if you use individual templates.

jQuery
index.js
$(function() {
    $("#listContainer").dxList({
        items: [{
            template: function () {
                return $("<i>").text("Item 1")
            }
        }, {
            template: function () {
                return $("<b>").text("Item 2")
            }
        },{
            template: function () {
                return $("<div>").append(
                    $("<span>").text("Item with nested component"),
                    $("<div>").dxButton({
                        text: "Click me"
                    })
                )
            }
        }]
    });
});
Angular

Declare named templates within the component's markup but outside the templated element. Non-named templates should be declared inside the templated element.

app.component.html
app.module.ts
<dx-list>
    <dxi-item>
        <i>Item 1</i>
    </dxi-item>
    <dxi-item>
        <b>Item 2</b>
    </dxi-item>
    <dxi-item>
        <div *dxTemplate>
            Item with a nested component
            <dx-button text="Click me"></dx-button>
        </div>
    </dxi-item>
</dx-list>
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { DxListModule, DxButtonModule } from 'devextreme-angular';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        DxListModule,
        DxButtonModule
    ],
    providers: [ ],
    bootstrap: [AppComponent]
})
export class AppModule { }
Vue

Declare named templates within the component's markup but outside the templated element. Non-named templates should be declared inside the templated element.

App.vue
<template>
    <DxList>
        <DxItem>
            <template #default>
                <i>Item 1</i>
            </template>
        </DxItem>
        <DxItem>
            <template #default>
                <i>Item 2</i>
            </template>
        </DxItem>
        <DxItem>
            <template #default>               
                <div>
                    Item with a nested component
                    <DxButton text="Click me" />
                </div>
            </template>
        </DxItem>
    </DxList>
</template>

<script>

import DxList, {
    DxItem
} from 'devextreme-vue/list';
import DxButton from 'devextreme-vue/button';

export default {
    components: {
        DxList,
        DxItem,
        DxButton
    }
}
</script>
React
App.js
import React from 'react';

import List, { Item } from 'devextreme-react/list';
import Button from 'devextreme-react/button';

class App extends React.Component {
    render() {

            <List>
                <Item>
                    <i>Item 1</i>

                <Item>
                    Item with a nested component
                    <Button text="Click me" />
                </Item>
            </List>
        );
    }
}
export default App;
