To underline a particular character in a text, it can be handled in beforeItemRender event by adding <u> tag in between the text and given as innerHTML in li rendering.

In the following example, C is underlined in the text Copy:

app.component.ts

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

@Component({
    selector: 'app-root',
    template:  `<div class="e-section-control">
                <!-- To Render splitbutton. -->
               <ejs-splitbutton content="Paste" [items]='items' (beforeItemRender)="itemRender($event)"></ejs-splitbutton></div>`
})

export class AppComponent {
    // Initialize action items.
    public items: ItemModel[] = [
        {
            text: 'Cut'
        },
        {
            text: 'Copy'
        },
        {
            text: 'Paste'
        }];
    public itemRender(args: MenuEventArgs) {
        if (args.item.text === 'Copy') {
            // To underline a particular text.
            args.element.innerHTML = '<u>C</u>opy';
        }
    }

}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { SplitButtonModule } from '@syncfusion/ej2-angular-splitbuttons';

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

main.ts

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

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
