我有这部分代码

<ngb-accordion #acc="ngbaccordion" closeOthers="true" type="'success'">
  <ngb-panel id="toggle-1" title="First panel">
   <ng-template ngbPanelContent>
    aaaaaaaaaaa
   </ng-template>
  </ngb-panel>
  <ngb-panel id="toggle-2" title="Second" >
   <ng-template ngbPanelContent>
    bbbbbbbbbbbb
   </ng-template>
  </ngb-panel>
 </ngb-accordion>

我如何在单击完整标题而不是仅在文本上进行切换？
