jQuery Gallery - Customize Item Appearance

Gallery items are not sctrictly images. They can contain text or other elements of your choice. For a minor customization of Gallery items, you can define specific fields in item data objects. For example, the following code generates two items: one is disabled and the other has a specified alt attribute.

jQuery
JavaScript
$(function () {
    $("#galleryContainer").dxGallery({
        dataSource: [{
            imageSrc: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person1.png",
            disabled: true
        }, {
            imageSrc: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person2.png",
            imageAlt: "Peter"
        }],
        height: 300
    });
});
Angular
HTML
TypeScript
<dx-gallery
    [dataSource]="galleryDataSource"
    [height]="300">
</dx-gallery>
import { DxGalleryModule } from "devextreme-angular";
// ...
export class AppComponent {
    galleryDataSource = [{
        imageSrc: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person1.png",
        disabled: true
    }, {
        imageSrc: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person2.png",
        imageAlt: "Peter"
    }];
}
@NgModule({
    imports: [
        // ...
        DxGalleryModule
    ],
    // ...
})
Vue
<template>
    <DxGallery
        :data-source="dataSource"
        :height="300"
    />
</template>

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

import { DxGallery } from 'devextreme-vue/gallery';

export default {
    components: {
        DxGallery
    },
    data() {
        return {
            dataSource: [{
                imageSrc: 'https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person1.png',
                disabled: true
            }, {
                imageSrc: 'https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person2.png',
                imageAlt: 'Peter'
            }]
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { Gallery } from 'devextreme-react/gallery';

const dataSource = [{
    imageSrc: 'https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person1.png',
    disabled: true
}, {
    imageSrc: 'https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person2.png',
    imageAlt: 'Peter'
}];

class App extends React.Component {
    render() {
        return (
            <Gallery
                dataSource={dataSource}
                height={300}
            />
        );
    }
}

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-gallery
    [dataSource]="galleryDataSource"
    [height]="300"
    itemTemplate="item">
    <div *dxTemplate="let data of 'item'">
        <p><b>Name</b>: <span>{{data.name}}</span></p>
        <img src="{{data.path}}" alt="{{data.name}}" />
    </div>
</dx-gallery>
import { DxGalleryModule } from "devextreme-angular";
// ...
export class AppComponent {
    galleryDataSource = [
        { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person1.png", name: "Maria" },
        { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person2.png", name: "John" },
        { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person3.png", name: "Xavier" }
    ];
}
@NgModule({
    imports: [
        // ...
        DxGalleryModule
    ],
    // ...
})
Vue
<template>
    <DxGallery
        :data-source="dataSource"
        :height="300"
        item-template="item">
        <template #item="{ data }">
            <div>
                <p><b>Name</b>: <span>{{data.name}}</span></p>
                <img :src="data.path" :alt="data.name" />
            </div>
        </template>
    </DxGallery>
</template>

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

import { DxGallery } from 'devextreme-vue/gallery';

export default {
    components: {
        DxGallery
    },
    data() {
        return {
            dataSource: [
                { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person1.png", name: "Maria" },
                { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person2.png", name: "John" },
                { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person3.png", name: "Xavier" }
            ]
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { Gallery } from 'devextreme-react/gallery';

const dataSource = [
    { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person1.png", name: "Maria" },
    { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person2.png", name: "John" },
    { path: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person3.png", name: "Xavier" }
];

const renderGalleryItem = (itemData) => {
    return (
        <div>
            <p><b>Name</b>: <span>{itemData.name}</span></p>
            <img src={itemData.path} alt={itemData.name} />
        </div>
    );
}

class App extends React.Component {
    render() {
        return (
            <Gallery
                dataSource={dataSource}
                height={300}
                itemRender={renderGalleryItem}
            />
        );
    }
}

export default App;

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

JavaScript
$(function () {
    $("#galleryContainer").dxGallery({
        dataSource: galleryData,
        height: 300,
        itemTemplate: function(e){
            e.itemElement.empty();
            e.itemElement.append("<p><b>Name</b>: " + e.itemData.name + "</p>");
            e.itemElement.append("<img src=\"" + e.itemData.path + "\" alt=\"" + e.itemData.name + "\"/>");
        }
    });
});

You can also customize an individual Gallery item. For this purpose, declare a template for this item as a script and pass its id to the template field of the item's data object.

HTML
JavaScript
<script id="individualTemplate" type="text/html">
    <!-- ... -->
</script>
const galleryData = [{
    imageSrc: "https://js.devexpress.com/Content/images/doc/20_2/PhoneJS/person1.png",
    imageAlt: "Maria",
    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.
