如何在angular 4中使用bootstrap nav-tab作为父子组件？

Question

我的代码看起来像这样，我想使用它作为父组件，所有其他选项卡都是子组件。我想把父组件的数据传递给所有的子组件，我该怎么做呢?请帮助

<section class="section_custom">
  <div class="container-fluid">
    <div class="card card-nav-tabs">
      <div class="card-header card-header-white">
        <div class="nav-tabs-navigation">
          <div class="nav-tabs-wrapper pull-right">
            <ul class="nav nav-tabs" data-tabs="tabs">
              <li class="nav-item">
                <a class="nav-link active" href="#details" data-toggle="tab">Candidate Details</a>
              </li>
              <li class="nav-item">
                <a [class]="id==null ?'nav-link disabled':'nav-link'" href="#profile" data-toggle="tab">Public Profile</a>
              </li>
              <li class="nav-item">
                <a [class]="id==null ?'nav-link disabled':'nav-link'" href="#login" data-toggle="tab">Account Settings</a>
              </li>
              <li class="nav-item">
                <a [class]="id==null ?'nav-link disabled':'nav-link'" href="#videos" data-toggle="tab">Videos</a>
              </li>
            </ul>
          </div>
        </div>
      </div>
      <div class="card-body">
        <div class="tab-content">
          <div class="tab-pane active" id="details">
            <app-candidate-edit></app-candidate-edit>
          </div>
          <div class="tab-pane" id="profile">
            <app-candidate-profile></app-candidate-profile>
          </div>
          <div class="tab-pane" id="login">
            <app-candidate-login></app-candidate-login>
          </div>
          <div class="tab-pane" id="videos">
            <app-candidate-video-list></app-candidate-video-list>
          </div>
        </div>
      </div>
    </div>
  </div>
</section>

如果能有更多的信息就好了。什么数据和到什么子组件。因为现在我只能想到这个。父itemId: number; comments: Array<{}>;中的<app-chat [comments]="comments" [itemId]="itemId"></app-chat>

在应用程序中-聊天<div *ngIf="comments" class="chatContainer" [style.display]="displayChat" > <!--Some more code--> </div>
