我想使用Angular Nebulal主题创建一个响应式顶部导航。我使用创建了顶部菜单

<nb-layout-header fixed>
    <nb-actions class="left">
        <nb-action class="profile" [nbContextMenu]="items" 
  nbContextMenuPlacement="bottom">Profile</nb-action>

        <nb-action [routerLink]="['/login']">Login</nb-action>
        <nb-action>menu 1</nb-action>
        <nb-action>menu 2</nb-action>
        <nb-action>secret menu</nb-action>
        <nb-action *ngIf="local.retrieve('loggedIn')">secret menu2</nb-action>
    </nb-actions>
</nb-layout-header>

但它在PC和移动设备上的布局是一样的。当用户在下面的类似移动设备的参考中浏览时,我如何使顶部导航栏成为“汉堡包”菜单

这是css和mediaQuery的问题。有几种方法,一种简单的方法,你定义了两种.css按钮响应和菜单响应

.button-responsive
{
    display:none
}

@media (max-width: 573px)
{
    .button-responsive
    {
        display:inline-block
    }
    .menu-responsive
    {
        display:none
    }
}

然后你可以有一个nb操作和一个nbContextMenu

  <nb-layout-header fixed>
    <!--add class button-responsive to the button-->
    <button nbButton ghost class="button-responsive" [nbContextMenu]="allitems">
      <nb-icon icon="menu-outline"></nb-icon>
    </button>
    <!--add class menu-responsive to nb-actions-->
    <nb-actions class="left menu-responsive">
      <nb-action class="profile" [nbContextMenu]="items" nbContextMenuPlacement="bottom">Profile</nb-action>
      <nb-action [routerLink]="['/login']">Login</nb-action>
      <nb-action>menu 1</nb-action>
      <nb-action>menu 2</nb-action>
      <nb-action>secret menu</nb-action>
    </nb-actions>
  </nb-layout-header>

更新使用固定侧杆的相同技术为此,在组件的构造函数中

constructor(public sidebarService: NbSidebarService) {}

我们的.html变成了这样

<nb-layout>
  <nb-layout-header fixed>
    <nb-icon class="button-responsive" icon="menu-outline" (click)="sidebarService.toggle()"></nb-icon>
    <nb-actions class="left menu-responsive">
      <nb-action class="profile" [nbContextMenu]="items" nbContextMenuPlacement="bottom">Profile</nb-action>
      <nb-action [routerLink]="['/login']">Login</nb-action>
      <nb-action>menu 1</nb-action>
      <nb-action>menu 2</nb-action>
      <nb-action>secret menu</nb-action>
    </nb-actions>
  </nb-layout-header>
  <nb-sidebar #sidebar state="collapsed" class="button-responsive" fixed>
    <nb-menu [items]="items"></nb-menu>
  </nb-sidebar>
