Icons in EJ2 TypeScript Drop down button control

31 Aug 202315 minutes to read

DropdownButton can have an icon to provide the visual representation of the action. To place the icon on a DropdownButton, set the iconCss property to e-icons with the required icon CSS. By default, the icon is positioned to the left side of the DropdownButton. You can customize the icon’s position using the iconPosition property.

In the following example, the DropdownButton with default iconPosition and iconPosition as Top is showcased:

import { DropDownButton, ItemModel } from '@syncfusion/ej2-splitbuttons';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize action items.
let items: ItemModel[] = [
    {
        text: 'Edit'
    },
    {
        text: 'Delete'
    },
    {
        text: 'Mark as Read'
    },
    {
        text: 'Like Message'
    }];
// To initialize the DropDownButton with icon.
let drpDownBtn: DropDownButton = new DropDownButton({ iconCss: 'ddb-icons e-message', items: items }, '#iconbutton');
// To position the icon to the top of the text on a DropDownButton.
let dropDownBtnObj: DropDownButton = new DropDownButton({ iconCss: 'ddb-icons e-message', items: items, iconPosition: 'Top' }, '#iconpstn');

import { DropDownButton, ItemModel, DropDownButtonModel } from '@syncfusion/ej2-splitbuttons';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize action items.
let items: ItemModel[] = [
    {

The Essential JS 2 provides a set of icons that can be loaded by applying e-icons class name to the element. You can also use third party icons on the DropDownButton using the iconCss property.

Sprite images can be loaded in DropDownButton instead of font icons using iconCss property.

In this following example, e-image class is added with background url of the sprite image along with X and Y positions. The width and
height of the element set as 32px.

import { DropDownButton, ItemModel, DropDownButtonModel } from '@syncfusion/ej2-splitbuttons';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize action items.
let items: ItemModel[] = [
    {
        text: 'Display Settings'
    },
    {
        text: 'System Settings'
    },
    {
        text: 'Additional Settings'
    }];

// Initialize DropDownButton options.
let options: DropDownButtonModel = {
  items: items,
  cssClass: 'e-caret-hide',
  iconCss: 'e-image'
};

// To initialize the DropDownButton with sprite image.
let drpDownBtn: DropDownButton = new DropDownButton(options);
drpDownBtn.appendTo('#icononly');

Vertical button in DropDownButton can be achieved by adding e-vertical class using cssClass property.

The following example illustrates how to provide vertical support in DropDownButton component.

import { DropDownButton, ItemModel } from '@syncfusion/ej2-splitbuttons';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize action items.
let items: ItemModel[] = [
    {
        text: 'Edit'
    },
    {
        text: 'Delete'
    },
    {
        text: 'Mark as Read'
    },
    {
        text: 'Like Message'
    }];

// To initialize the vertical DropDownButton.
let drpDownBtn: DropDownButton = new DropDownButton({ iconCss: 'ddb-icons e-message', cssClass: 'e-vertical', items: items, iconPosition: 'Top' }, '#iconbutton');
