如何在angular 2的ng2-tag-input下拉菜单中添加一个按钮？

npm install ng2-tag-input

import { Component } from '@angular/core';
import { TagInputModule } from 'ng2-tag-input';

@Component({
  selector: 'app-your-component',
  template: `
    <tag-input [(ngModel)]="tags">
      <tag-input-dropdown [showDropdownIfEmpty]="true">
        <ng-template let-item="item" let-index="index">
          {{ item }}
          <button (click)="handleButtonClick(item)">按钮</button>
        </ng-template>
      </tag-input-dropdown>
    </tag-input>
  `,
  styleUrls: ['./your-component.component.css']
})
export class YourComponent {
  tags = ['tag1', 'tag2', 'tag3'];

  handleButtonClick(item: string) {
    console.log('按钮被点击，当前项：', item);
    // 在这里添加你的逻辑代码
  }
}
