Angular2材料设计循环中的下拉菜单

Question

我循环遍历一个数组（serviceOptions），对于每个选项，我都有一个下拉列表。下降是自动完成的。当我在任何下拉列表中选择某个选项时，会显示所有下拉列表。问题是由于[mdAutocomplete] =＆＃34; package＆＃34;。我需要改变这个＆＃34;包＆＃34;在#package =＆＃34; mdAutocomplete＆＃34;在。 有帮助吗？

<label *ngFor="let service of serviceOptions">
    {{service.serviceName}}
    <br/>
    <md-input-container class="autoCompolete">
      <input mdInput placeholder="Select Package" [mdAutocomplete]="package" [formControl]="packageCtrl" formControlName="packageName" [(ngModel)]="currentpackage" size="30">
    </md-input-container>
    <md-autocomplete #package="mdAutocomplete" [displayWith]="displayPackage">
        <md-option (onSelectionChange)="packageSelection($event, package)" [value]="package" *ngFor="let package of (reactivePackages | async)">
          {{ package.packageName }}
          {{package.serviceId}}
          {{service.serviceId}}
        </md-option>
    </md-autocomplete>
    <br />
  </label>
