Icons

The popup action item have an icon or image to provide visual representation of the action. To place the icon on a popup item, set the iconCss property to e-icons with the required icon CSS. By default, the icon is positioned to the left side of the popup action item.

In the following sample, the icons for edit, delete, mark as read and like message menu items are added using the iconCss property.

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DropDownButtonModule } from '@syncfusion/ej2-angular-splitbuttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';
import { ItemModel } from '@syncfusion/ej2-angular-splitbuttons';

@Component({
imports: [
        
        DropDownButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render DropDownButton. -->
               <button ejs-dropdownbutton [items]='items' content='Message' iconCss='ddb-icons e-message'></button></div>`
})

export class AppComponent {
   // Initialize action items.
   public items: ItemModel[] = [
    {
        text: 'Edit',
        iconCss: 'ddb-icons e-edit'
    },
    {
        text: 'Delete',
        iconCss: 'ddb-icons e-delete'
    },
    {
        text: 'Mark As Read',
        iconCss: 'ddb-icons e-read'
    },
    {
        text: 'Like Message',
        iconCss: 'ddb-icons e-like'
    }];

}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Navigations

Actions in DropDownButton can be used to navigate to the other web page when action item is clicked. This can be achieved by providing link to the action item using url property.

In the following sample, navigation URL for Flipkart, Amazon, and Snapdeal action items are added using the url property:

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DropDownButtonModule } from '@syncfusion/ej2-angular-splitbuttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';
import { ItemModel, MenuEventArgs } from '@syncfusion/ej2-angular-splitbuttons';

@Component({
imports: [
        
        DropDownButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render DropDownButton. -->
               <button ejs-dropdownbutton [items]='items' content='Shop By' iconCss='e-cart-icon e-shopping' (beforeItemRender)='itemBeforeEvent($event)'></button></div>`
})

export class AppComponent {
   // Initialize action items.
   public items: ItemModel[] = [
    {
        text: 'Flipkart',
        iconCss: 'e-cart-icon e-link',
        url: 'https://www.google.co.in/search?q=flipkart'
    },
    {
        text: 'Amazon',
        iconCss: 'e-cart-icon e-link',
        url: 'https://www.google.co.in/search?q=amazon'
    },
    {
        text: 'Snapdeal',
        iconCss: 'e-cart-icon e-link',
        url: 'https://www.google.co.in/search?q=snapdeal'
    }];
    // To open the url in the blank page.
    public itemBeforeEvent (args: MenuEventArgs) {
        args.element.getElementsByTagName('a')[0].setAttribute('target', '_blank');
    }

}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Template

Item templating

Popup items can be customized using the beforeItemRender event. The item render event triggers while rendering each popup action item. The event argument will be used to identify the action item and customize based on the requirement.

The following popup template is customized using beforeItemRender event by appending span and div element on each li rendering:

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DropDownButtonModule } from '@syncfusion/ej2-angular-splitbuttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';
import { ItemModel, MenuEventArgs } from '@syncfusion/ej2-angular-splitbuttons';

@Component({
imports: [
        
        DropDownButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render DropDownButton. -->
               <button ejs-dropdownbutton [items]='items' content='Paste' iconCss='e-ddb-icons e-paste' iconPosition='Top' cssClass='e-vertical' (beforeItemRender)='itemBeforeEvent($event)'></button></div>`
})

export class AppComponent {
   // Initialize action items.
   public items: ItemModel[] = [
    {
        text: 'Edit'
    },
    {
        text: 'Cut'
    }];

    public itemBeforeEvent (args: MenuEventArgs) {
    // To append span and div element in each li rendering.
    if (args.item.text === 'Edit') {
      args.element.innerHTML = '<span></span><div><b>Paste Text</b><div>Provides option to paste only the<br>selected text.</div></div>';
      args.element.style.height = '80px';
      let span: Element = args.element.children[0];
      span.setAttribute('class','e-cm-icons e-pastetext e-align');
      let div: Element = args.element.children[1];
      div.setAttribute('class', 'e-div-align');
    } else {
      args.element.innerHTML = '<span></span><div><b>Paste Special</b><div>Provides options to paste formulas,<br> values, comments, validations etc...</div></div>';
      args.element.style.height = '80px';
      let span: Element = args.element.children[0];
      span.setAttribute('class','e-cm-icons e-pastespecial e-align');
      let div: Element = args.element.children[1];
      div.setAttribute('class', 'e-div-align');
    }
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

The whole popup can be customized as per the requirement. In the following example, the popup can be customized by handling it in target property.

In the following sample, the whole popup item is customized as table template by giving div as target and it can be achieved using target property.

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DropDownButtonModule } from '@syncfusion/ej2-angular-splitbuttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';

@Component({
imports: [
        
        DropDownButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- Target element to DropDownButton . -->
               <div id="target" style='border: 1px solid #999;'>
               <!-- To create table. -->
               <table>
               <caption style='height: 18px; background-color: #e0e0e0;'><b>Insert Table</b></caption>
                    <tr class='e-row'>
                        <td class='e-data'></td>
                        <td class='e-data'></td>

})

export class AppComponent {

Separator

The Separators are the horizontal lines that are used to separate the popup items. You cannot select the separators.
You can enable separators to group the popup items using the separator property.

In the following sample, cut, copy, and paste popup items are grouped using the separator property:

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { DropDownButtonModule } from '@syncfusion/ej2-angular-splitbuttons'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component } from '@angular/core';
import { ItemModel } from '@syncfusion/ej2-angular-splitbuttons';

@Component({
imports: [
        
        DropDownButtonModule
    ],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
                <!-- To render DropDownButton. -->
               <button ejs-dropdownbutton [items]='items' content='Clipboard' iconCss='e-icons e-edit'></button></div>`
})

export class AppComponent {
   // Initialize action items.
   public items: ItemModel[] = [
    {
        text: 'Cut',
        iconCss: 'e-db-icons e-cut'
    },
    {
        text: 'Copy',
        iconCss: 'e-icons e-copy'
    },
    {
        text: 'Paste',
        iconCss: 'e-db-icons e-paste'
    },
    {
        separator: true
    },
    {
        text: 'Font',
        iconCss: 'e-db-icons e-font'
    },
    {
        text: 'Paragraph',
        iconCss: 'e-db-icons e-paragraph'
    }];
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
