You can render icons to the list items by mapping the iconCss  fields. This iconCss field create a span in the list item with mapped class name to allow styling as per your need.

In the following sample, icon classes are mapped with iconCss field.

app.component.ts

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

@Component({
    selector: 'app-root',
    // specifies the template string for the ComboBox component.
    template: `<ejs-combobox id='comboelement' #samples [dataSource]='data' [fields]='fields' [placeholder]='text'></ejs-combobox>`
})
export class AppComponent {
    constructor() {
    }
    // defined the array of data
    public data: { [key: string]: Object }[] = [
        { Class: 'asc-sort', Type: 'Sort A to Z', Id: '1' },
        { Class: 'dsc-sort', Type: 'Sort Z to A ', Id: '2' },
        { Class: 'filter', Type: 'Filter', Id: '3' },
        { Class: 'clear', Type: 'Clear', Id: '4' }];
    // map the icon column to iconCSS field.
    public fields: Object = { text: 'Type', iconCss: 'Class', value: 'Id' };
    //set the placeholder to ComboBox input
    public text: string = 'Select a format';
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { ComboBoxModule } from '@syncfusion/ej2-angular-dropdowns';
/**

 */
@NgModule({
    imports: [
        BrowserModule,FormsModule, ComboBoxModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
