Angular Accordion - Customize Item Appearance

For a minor customization of Accordion panels, you can define specific fields in panel data objects. For example, the following code generates three panels, the first and third are not customized, the second is disabled.

jQuery
JavaScript
HTML
var accordionData = [{
    title: "Employee",
    text: "John Smith"
}, {
    title: "Phone Number",
    text: "(555)555-5555",
    disabled: true
}, {
    title: "Position",
    text: "Network Administrator"
}];

$(function () {
    $("#accordionContainer").dxAccordion({
        dataSource: accordionData
    });
});
<div id="accordionContainer"></div>
Angular
HTML
TypeScript
<dx-accordion
    [dataSource]="accordionData">
</dx-accordion>
import { DxAccordionModule } from "devextreme-angular";
// ...
export class AppComponent {
    accordionData = [{
        title: "Employee",
        text: "John Smith"
    }, {
        title: "Phone Number",
        text: "(555)555-5555",
        disabled: true
    }, {
        title: "Position",
        text: "Network Administrator"
    }];
}
@NgModule({
    imports: [
        // ...
        DxAccordionModule
    ],
    // ...
})
Vue
App.vue
<template>
    <DxAccordion
        :data-source="accordionData">
    </DxAccordion>
</template>
<script>
import 'devextreme/dist/css/dx.light.css';

import DxAccordion from "devextreme-vue/accordion";

export default {
    components: {
        DxAccordion
    },
    data() {
        return {
            accordionData: [{
                title: "Employee",
                text: "John Smith"
            }, {
                title: "Phone Number",
                text: "(555)555-5555",
                disabled: true
            }, {
                title: "Position",
                text: "Network Administrator"
            }]
        };
    }
};
</script>
React
App.js
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import { Accordion } from 'devextreme-react/accordion';

const accordionData = [{
    title: "Employee",
    text: "John Smith"
}, {
    title: "Phone Number",
    text: "(555)555-5555",
    disabled: true
}, {
    title: "Position",
    text: "Network Administrator"
}];

class App extends React.Component {
    render() {
        return (
            <Accordion
                dataSource={accordionData}
            />
        );
    }
}

export default App;

If you need a more flexible solution, define an itemTemplate and itemTitleTemplate:

jQuery
JavaScript
HTML
var accordionData = [{
    firstName: "John", lastName: "Smith",
    birthDate: "1986/03/14",
    position: "Network Administrator"
}, {
    firstName: "Samantha", lastName: "Jones",
    birthDate: "1972/11/13",
    position: "Technical Writer"
}];

$(function () {
    $("#accordionContainer").dxAccordion({
        dataSource: accordionData,
        itemTemplate: function (itemData, itemIndex, itemElement) {
            itemElement.append("<p>" + itemData.birthDate + "&nbsp;</p>");
            itemElement.append("<p>" + itemData.position + "</p>");
        },
        itemTitleTemplate: function (itemData, itemIndex, itemElement) {
            itemElement.append("<span>" + itemData.firstName + "&nbsp;</span> ");
            itemElement.append("<span>" + itemData.lastName + "</span>");
        }
    });
});
<div id="accordionContainer"></div>

        <span>{{employee.lastName}}</span>

jQuery

You can also customize individual items. Declare the items as scripts and reference them in the template property or assign a customization function straight to this property:

HTML
JavaScript
<div id="accordionContainer"></div>
<script id="individualTemplate" type="text/html">
    <span>Technical Writer</span>
</script>
$(function() {
    $("#accordionContainer").dxAccordion({
        items: [{
            title: "John Smith",
            template: function() {
                return $("<span>").text("Network Administrator");
            }
        }, {
            title: "Samantha Jones",
            template: $("#individualTemplate")
        }]
    });
});
Angular

You can also customize individual items. Declare them using the dxItem component:

HTML

    </dxi-item>
    <dxi-item title="Samantha Jones">
        <span>Technical Writer</span>
    </dxi-item>
</dx-accordion>
import { DxAccordionModule } from "devextreme-angular";
// ...
export class AppComponent {

        DxAccordionModule
    ],
    // ...
})
Vue

You can also customize individual items. Declare them using the dxItem component:

                <div>Network Administrator</div>
            </template>
        </DxItem>
        <DxItem title="Samantha Jones">
            <template #default>
                <div>Technical Writer</div>
            </template>
        </DxItem>
    </DxAccordion>
</template>
<script>
import 'devextreme/dist/css/dx.light.css';

export default {
    components: {
        DxAccordion,
        DxItem
    }
};
</script>
React

You can also customize individual items. Declare them using the dxItem component:

App.js
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

class App extends React.Component {
    render() {

                </Item>
                <Item title="Samantha Jones">
                    <span>Technical Writer</span>
                </Item>
            </Accordion>
        );
