Vue 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. In Angular and Vue, you can declare it in the markup. In React, you can use a rendering function (shown in the code below) or component

Angular
HTML
TypeScript
<dx-accordion
    [dataSource]="accordionData"
    itemTitleTemplate="title"
    itemTemplate="item">
    <div *dxTemplate="let employee of 'title'">
        <span>{{employee.firstName}}&nbsp;</span>
        <span>{{employee.lastName}}</span>
    </div>
    <div *dxTemplate="let employee of 'item'">
        <span>{{employee.birthDate}}&nbsp;</span>
        <span>{{employee.position}}</span>
    </div>
</dx-accordion>
import { DxAccordionModule } from "devextreme-angular";
// ...
export class AppComponent {
    accordionData = [{
        firstName: "John", lastName: "Smith",
        birthDate: "1986/03/14",
        position: "Network Administrator"
    }, {
        firstName: "Samantha", lastName: "Jones",
        birthDate: "1972/11/13",
        position: "Technical Writer"
    }];
}
@NgModule({
    imports: [
        // ...
        DxAccordionModule
    ],
    // ...
})
Vue
App.vue
<template>
    <DxAccordion
        :data-source="accordionData"
        item-title-template="title"
        item-template="item">
        <template #title="{ data }">
            <div>
                <span>{{ data.firstName }}&nbsp;</span>
                <span>{{ data.lastName }}</span>
            </div>
        </template>
        <template #item="{ data }">
            <div>
                <span>{{ data.birthDate }}&nbsp;</span>
                <span>{{ data.position }}</span>
            </div>
        </template>
    </DxAccordion>
</template>
<script>
import 'devextreme/dist/css/dx.light.css';

import DxAccordion from "devextreme-vue/accordion";

export default {
    components: {
        DxAccordion
    },
    data() {
        return {
            accordionData: [{
                firstName: "John", lastName: "Smith",
                birthDate: "1986/03/14",
                position: "Network Administrator"
            }, {
                firstName: "Samantha", lastName: "Jones",
                birthDate: "1972/11/13",
                position: "Technical Writer"
            }];
        };
    }
};
</script>
React
App.js
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

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

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

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

    renderTitle(data) {
        return (
            <div>
                <span>{data.firstName}&nbsp;</span>
                <span>{data.lastName}</span>
            </div>
        );
    }

    renderItem(data) {
        return (
            <div>
                <span>{data.birthDate}&nbsp;</span>
                <span>{data.position}</span>
            </div>
        );
    }
}

export default App;

If you use jQuery, use DOM manipulation methods to combine the HTML markup for accordion item. To apply this markup, use the itemTemplate and itemTitleTemplate callback functions as shown in the following code:

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>

You can also customize individual items. In Angular, Vue, and React, declare them using the dxItem component. When using jQuery, you can declare the items as scripts and reference them in the template property or assign a customization function straight to this property.

Angular
HTML
TypeScript
<dx-accordion>
    <dxi-item title="John Smith">
        <span>Network Administrator</span>
    </dxi-item>
    <dxi-item title="Samantha Jones">
        <span>Technical Writer</span>
    </dxi-item>
</dx-accordion>
import { DxAccordionModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxAccordionModule
    ],
    // ...
})
Vue
App.vue
<template>
    <DxAccordion>
        <DxItem title="John Smith">
            <template #default>
                <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';

import DxAccordion, { DxItem } from "devextreme-vue/accordion";

export default {
    components: {
        DxAccordion,
        DxItem
    }
};
</script>
React
App.js
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

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

class App extends React.Component {
    render() {
        return (
            <Accordion>
                <Item title="John Smith">
                    <span>Network Administrator</span>
                </Item>
                <Item title="Samantha Jones">
                    <span>Technical Writer</span>
                </Item>
            </Accordion>
        );
    }
}

export default App;
jQuery
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")
        }]
    });
});

In addition, you can use a 3rd-party template engine to customize UI component appearance. For more information, see the 3rd-Party Template Engines article.
