angular2中的模板覆盖

你能告诉我如何覆盖 angular2 模板吗？有一个选择框模块 ng2-select。在这个模块中，您需要更改模板：添加一个自定义滚动条（ng2-slimscroll），稍微更改一下布局。问题是如何在angular2中实现这个？现在组件看起来像这样：

import {  Component } from '@angular/core';
import {CORE_DIRECTIVES, FORM_DIRECTIVES, NgClass} from '@angular/common';

import {BUTTON_DIRECTIVES } from 'ng2-bootstrap/ng2-bootstrap';
import {SELECT_DIRECTIVES } from 'ng2-select/ng2-select';

import {BaseComponent} from '../base/base.component';


@Component({
selector: 'content',
templateUrl: 'app/admin/generation/generation.component.html',
directives: [SELECT_DIRECTIVES],
styleUrls: ['../../node_modules/ng2-select/components/css/ng2-select.css']
})

export class GenerationComponent  {

public items:Array<string> = ['Amsterdam', 'Antwerp', 'Athens', 'Barcelona',
    'Berlin', 'Birmingham', 'Bradford', 'Bremen', 'Brussels', 'Bucharest',
    'Budapest', 'Cologne', 'Copenhagen', 'Dortmund', 'Dresden', 'Dublin',
    'Düsseldorf', 'Essen', 'Frankfurt', 'Genoa', 'Glasgow', 'Gothenburg',
    'Hamburg', 'Hannover', 'Helsinki', 'Kraków', 'Leeds', 'Leipzig', 'Lisbon',
    'London', 'Madrid', 'Manchester', 'Marseille', 'Milan', 'Munich', 'Málaga',
    'Naples', 'Palermo', 'Paris', 'Poznań', 'Prague', 'Riga', 'Rome',
    'Rotterdam', 'Seville', 'Sheffield', 'Sofia', 'Stockholm', 'Stuttgart',
    'The Hague', 'Turin', 'Valencia', 'Vienna', 'Vilnius', 'Warsaw', 'Wrocław',
    'Zagreb', 'Zaragoza', 'Łódź'];

private value:any = {};
private _disabledV:string = '0';
private disabled:boolean = false;

private get disabledV():string {
    return this._disabledV;
}

private set disabledV(value:string) {
    this._disabledV = value;
    this.disabled = this._disabledV === '1';
}

public selected(value:any):void {
    console.log('Selected value is: ', value);
}

public removed(value:any):void {
    console.log('Removed value is: ', value);
}

public typed(value:any):void {
    console.log('New search input: ', value);
}

public refreshValue(value:any):void {
    this.value = value;
}

}
