Vue RadioGroup - Customize Item Appearance

For a minor customization of RadioGroup items, you can define specific fields in item data objects. For example, the following code generates three radio buttons: the first is disabled, the second is not customized, the third is hidden.

jQuery
JavaScript
$(function() {
    $("#radioGroupContainer").dxRadioGroup({
        dataSource: [
            { text: "Low", disabled: true },
            { text: "High" },
            { text: "Urgent", visible: false }
        ]
    });
});
Angular
HTML
TypeScript
<dx-radio-group
    [dataSource]="dataSource">
</dx-radio-group>
import { DxRadioGroupModule } from "devextreme-angular";
// ...
export class AppComponent {
    dataSource = [
        { text: "Low", disabled: true },
        { text: "High" },
        { text: "Urgent", visible: false }
    ]
}
@NgModule({
    imports: [
        // ...
        DxRadioGroupModule
    ],
    // ...
})
Vue
<template>
    <DxRadioGroup :data-source="dataSource"/>
</template>

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

import { DxRadioGroup } from 'devextreme-vue/radio-group';

export default {
    components: {
        DxRadioGroup
    },
    data() {
        return {
            dataSource: [
                { text: 'Low', disabled: true },
                { text: 'High' },
                { text: 'Urgent', visible: false }
            ]
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { RadioGroup } from 'devextreme-react/radio-group';

const dataSource = [
    { text: 'Low', disabled: true },
    { text: 'High' },
    { text: 'Urgent', visible: false }
];

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

export default App;

If you need a more flexible solution, define an itemTemplate. 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-radio-group 
    [dataSource]="dataSource"
    itemTemplate="radio">
    <div class="radio" *dxTemplate="let data of 'radio'">
        <p style="font-size:larger"><b>{{data}}</b></p>
    </div>
</dx-radio-group>
import { DxRadioGroupModule } from "devextreme-angular";
// ...
export class AppComponent {
    dataSource = ["Low", "Normal", "Urgent", "High"]
}
@NgModule({
    imports: [
        // ...
        DxRadioGroupModule
    ],
    // ...
})
Vue
<template>
    <DxRadioGroup
        :data-source="dataSource"
        item-template="radio">
        <template #radio="{ data }">
            <div>
                <p style="font-size:larger"><b>{{data}}</b></p>
            </div>
        </template>
    </DxRadioGroup>
</template>

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

import { DxRadioGroup } from 'devextreme-vue/radio-group';

export default {
    components: {
        DxRadioGroup
    },
    data() {
        return {
            dataSource: ['Low', 'Normal', 'Urgent', 'High']
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { RadioGroup } from 'devextreme-react/radio-group';

const dataSource = ['Low', 'Normal', 'Urgent', 'High'];

const renderRadioGroupItem = (itemData) => {
    return (
        <div>
            <p style={{fontSize: "larger"}}><b>{itemData}</b></p>
        </div>
    );
}

class App extends React.Component {
    render() {
        return (
            <RadioGroup
                dataSource={dataSource}
                itemRender={renderRadioGroupItem}
            />
        );
    }
}

export default App;

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

JavaScript
$(function() {
    $("#radioGroupContainer").dxRadioGroup({
        dataSource: [
            { text: "Low", color: "grey" },
            { text: "Normal", color: "green" },
            { text: "Urgent", color: "yellow" },
            { text: "High", color: "red" }
        ],
        itemTemplate: function(itemData, itemIndex, itemElement){
            itemElement.append(
                $("<div />").attr("style", "color:" + itemData.color )
                            .text(itemData.text)
            );
        }
    });
});

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

HTML
JavaScript
<script id="individualTemplate" type="text/html">
    <!-- ... -->
</script>
const radioGroupItems = [{
    text: "Low",
    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.
