Gallery Items in EJ2 TypeScript Ribbon Control

21 Mar 202424 minutes to read

The Ribbon supports Gallery view which allows users to perform specific actions by displaying a collection of related items, including icons, content, or images. You can render the gallery item by setting the type property to Gallery and customize it by using the RibbonGallerySettingsModel, which provides options such as groups, itemCount, popupHeight, popupWidth and more.

Groups

You can render the groups inside the gallery items by using groups property and customize the groups using RibbonGalleryGroupModel, which provides options such as items, cssClass, header and more.

Adding items

You can render the gallery items by using items property and customize using the RibbonGalleryItemModel, which provides options such as content, iconCss, disabled and more.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

let tabs: RibbonTabModel[] = [
  {

    groups: [

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

Adding html attributes

You can use the htmlAttributes property to add HTML attributes to the Ribbon gallery item.

The following sample showcases how to add title attribute to the gallery item using htmlAttributes property.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

let tabs: RibbonTabModel[] = [
  {
    header: "Home",
    groups: [
      {
        header: "Clipboard",
        groupIconCss: 'e-icons e-paste',
        collections: [{
            items: [{
                type: RibbonItemType.SplitButton,
                splitButtonSettings: {
                    iconCss: 'e-icons e-paste',
                    items: [{ text: 'Keep Source Format' }, { text: 'Merge Format' }, { text: 'Keep Text Only' }],
                    content: 'Paste'
                }
            }]
        }, {
            items: [{
                type: RibbonItemType.Button,
                buttonSettings: {
                    content: 'Cut',
                    iconCss: 'e-icons e-cut'
                }
            }, {

                    iconCss: 'e-icons e-copy'
                }
            }, {

Css class

You can use the cssClass property to customize the gallery item.

The following sample showcases how to customize the appearance of each gallery item using the cssClass property .

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

let tabs: RibbonTabModel[] = [
  {
    header: "Home",
    groups: [
      {
        header: "Clipboard",
        groupIconCss: 'e-icons e-paste',
        collections: [{
            items: [{
                type: RibbonItemType.SplitButton,
                splitButtonSettings: {
                    iconCss: 'e-icons e-paste',
                    items: [{ text: 'Keep Source Format' }, { text: 'Merge Format' }, { text: 'Keep Text Only' }],
                    content: 'Paste'
                }
            }]
        }, {

Disabled

You can use the disabled property to disable the Ribbon gallery item. It prevents the user interaction when set to true. By default, the value is false.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Custom header

You can use the header property to set header for the group items in the Ribbon gallery popup.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

let tabs: RibbonTabModel[] = [

Setting item width

You can use the itemWidth property to specify the width of gallery items.

Setting item height

You can use the itemHeight property to set the height of the gallery items. If the itemHeight of the gallery item is smaller the remaining gallery items are aligned based on the itemCount specified.

The provided example demonstrates how to customize gallery items using the itemWidth and itemHeight properties.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

let tabs: RibbonTabModel[] = [
  {
    header: "Home",
    groups: [
      {
        header: "Clipboard",
        groupIconCss: 'e-icons e-paste',
        collections: [{
            items: [{
                type: RibbonItemType.SplitButton,
                splitButtonSettings: {
                    iconCss: 'e-icons e-paste',
                    items: [{ text: 'Keep Source Format' }, { text: 'Merge Format' }, { text: 'Keep Text Only' }],
                    content: 'Paste'
                }
            }]
        }, {
            items: [{
                type: RibbonItemType.Button,
                buttonSettings: {
                    content: 'Cut',
                    iconCss: 'e-icons e-cut'

Group styling

You can use the cssClass property to customize the appearance of gallery groups.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

                  groups: [{
                    header: 'Styles',
                    cssClass: "custom-group",

                  }]
                }
              }
            ]
          }
        ]
      }

Setting item count

You can customize the number if items to be displayed in Ribbon gallery by using the itemCount property. By default the itemCount will be 3.

The following example showcases the utilization of the itemCount property, displaying a ribbon gallery with 4 items.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

let tabs: RibbonTabModel[] = [
  {
    header: "Home",
    groups: [
      {
        header: "Clipboard",
        groupIconCss: 'e-icons e-paste',
        collections: [{
            items: [{
                type: RibbonItemType.SplitButton,
                splitButtonSettings: {
                    iconCss: 'e-icons e-paste',
                    items: [{ text: 'Keep Source Format' }, { text: 'Merge Format' }, { text: 'Keep Text Only' }],
                    content: 'Paste'
                }
            }]
        }, {
            items: [{
                type: RibbonItemType.Button,
                buttonSettings: {
                    content: 'Cut',

              {
                type: RibbonItemType.Gallery,
                gallerySettings: {
                  itemCount: 4,

Setting selected item

You can use the selectedItemIndex property to define the currently selected item in the Ribbon gallery items.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

let tabs: RibbonTabModel[] = [
  {
    header: "Home",
    groups: [
      {
        header: "Clipboard",
        groupIconCss: 'e-icons e-paste',
        collections: [{
            items: [{

Setting popup width

you can specify the width of the gallery popup by using the popupWidth propery.

The example demonstrates the customization of popup with popupHeight and popupWidth properties.

import { Ribbon, RibbonTabModel, RibbonItemType, RibbonGallery } from "@syncfusion/ej2-ribbon";

Ribbon.Inject(RibbonGallery);

let tabs: RibbonTabModel[] = [
  {
    header: "Home",
    groups: [

You can customize the default appearance and content of Ribbon gallery items by using the template property.

You can customize the appearance of Ribbon gallery popup by using the popupTemplate property.

The below example demonstrates the customization of both the template and popupTemplate properties:

Ribbon.Inject(RibbonGallery);
