我在nav.component.html中单独创建了导航栏,如何在某些组件中隐藏导航栏,例如login.component.

nav.component.html

<nav class="navbar navbar-default navbar-fixed-top navClass">
    <div class="container-fluid">
        <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed"
                        (click)="toggleState()">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>

        </div>
         <div class="collapse navbar-collapse"
              [ngClass]="{ 'in': isIn }">
          enter code here   <ul class="nav navbar-nav">
               <li class="active"><a href="#">Home</a></li>
               <li><a href="#">about</a></li>

            </ul>

        </div>
    </div>
</nav>
