如何填充多选下拉列表

Question

我多次尝试从服务中填充ng-multiselect-dropdown，但均未成功。 有人可以帮我吗？

服务-----

     getClients(): Observable<Client[]> {
     return this.HttpClient.get<Client[]>('/api/clients');
     }

组件-----

    this.clientService.getClients()
    .subscribe(data => {
    this.dropdownList = data;
     this.clientDropdownList.push({ '_id': data, 'name': data}) ,
      console.log(this.dropdownList)
     }
     )};

html -----

    <ng-multiselect-dropdown class="customDropdown" 
    formControlName="client"
    [placeholder]="'Select Client'"
    [data]="clientDropdownList" 
    [(ngModel)]="selectedItems" 
    [settings]="dropdownSettings"
    (onSelect)="onItemSelect($event)"
    (onSelectAll)="onSelectAll($event)">
    </ng-multiselect-dropdown>

控制台日志------我有我的所有客户

    (6) [{…}, {…}, {…}, {…}, {…}, {…}]
    0: {_id: "5c5f8914b8e5a56058a4e16a", name: "*****randji", address: 
     "******", email: "*********", phone: "**********", …}
    length: 6
   __proto__: Array(0)

我只需要在下拉列表中填充客户的名称。

谢谢大家
