在angular2中扩展模板

Question

请帮帮我。我有ng2-select模块。在这个模块中，大多数添加滚动条模块（ng2-slimscroll）并通过设计选择框添加我的布局。我想在该模块中扩展和覆盖模板。 我的代码现在：

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;
    }
}
