创建具有两行的响应式 Bootstrap 导航栏 [英] Create responsive Bootstrap navbar with two rows

问题描述

我正在尝试创建一个具有两行的响应式 Bootstrap 3 导航栏.但是，我在 HTML 的结构和折叠功能方面遇到了问题.

以下是对所需结果的直观描述，我希望有人能在 HTML/CSS 方面为我指明正确的方向(使用尽可能多的默认 Bootstrap 功能).

基本上菜单需要执行以下操作:

• 在平板电脑/桌面设备上，第一行是徽标和菜单小的辅助链接(Link1-3).第二行是主菜单主要链接(LinkA-E).

• 在移动设备上，经典的折叠设计应该与徽标和汉堡包图标一起出现.展开的菜单应该先显示主链接(LinkA-E)，然后显示次链接(Link1-3) 最后.

平板电脑/桌面设备:

|----------------------------------------------------------||LOGO/品牌链接1 链接2 链接3 ||----------------------------------------------------------||LinkA LinkB LinkC LindD LinkE ||----------------------------------------------------------|

移动设备(折叠):

|--------------------------------------||标志/品牌汉堡 ||--------------------------------------|

移动设备(扩展):

|--------------------------------------||标志/品牌汉堡 ||--------------------------------------||友情链接|友情链接 ||友情链接 ||友情链接 ||领英 ||--------------------------------------||链接1 ||链接2 ||链接3 ||--------------------------------------|

解决方案

如果我有你项目的 html/css，我会用它来展示你应该如何做，但在这种情况下这个 HTML 来自 Bootstrap v3.3.7 的静态导航栏示例

实际上的想法是将 <div id="navbar" class="navbar-collapse collapse"> 放在 <div class="navbar-header"> 下方的行中; 使用浮动和宽度 100% 的空间，然后使用 margin-top 拉起

:-50px;

通过该媒体查询，我们可以确保它在移动设备中的行为正确.

HTML

<div class="navbar-header"><button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"><span class="sr-only">切换导航</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span><a class="navbar-brand" href="#">标志/品牌</a>
<div id="navbar" class="navbar-collapse collapse"><ul class="nav navbar-nav"><li><a href="#">LinkA</a></li><li><a href="#">LinkB</a></li><li><a href="#">LinkC</a></li><li><a href="#">LinkD</a></li><li><a href="#">LinkE</a></li>

<ul class="nav navbar-nav navbar-right"><li><a href="#">Link1</a></li><li><a href="#">Link2</a></li><li><a href="#">Link3</a></li></div><!--/.nav-collapse -->

CSS

.navbar-collapse {向左飘浮;宽度:100%；清楚:两者；}@media(最小宽度:768px){.navbar-右{边距顶部:-50px；}}

只是让我知道它是否有效.

I am trying to create a responsive Bootstrap 3 based navbar with two rows. However, I am having trouble with the structure of the HTML and the collapse functionality.

Below is a visual description of the desired result, and I was hoping someone could point me in the right direction in terms of HTML/CSS (with as much default Bootstrap functionality as possible).

Essentially the menu is desired to do the following:

• On tablet/desktop devices, the first row is the logo and a menu of small secondary links (Link1-3). The second row is the main menu with main links (LinkA-E).

• On mobile, the classic collapse design should appear with the logo and hamburger icon. The expanded menu should show the main links (LinkA-E) first, and then the secondary links (Link1-3) last.

Tablet/Desktop device:

|----------------------------------------------------------|
|  LOGO/BRAND                         Link1  Link2  Link3  |
|----------------------------------------------------------|
|  LinkA  LinkB  LinkC  LindD  LinkE                       |
|----------------------------------------------------------|

Mobile device (collapsed):

|--------------------------------------|
|  LOGO/BRAND               HAMBURGER  |
|--------------------------------------|

Mobile device (expanded):

|--------------------------------------|
|  LOGO/BRAND               HAMBURGER  |
|--------------------------------------|
|  LinkA                               |
|  LinkB                               |
|  LinkC                               |
|  LinkD                               |
|  LinkE                               |
|--------------------------------------|
|  Link1                               |
|  Link2                               |
|  Link3                               |
|--------------------------------------|

解决方案

If i had an html/css of your project i use it to show how you should do that, but in this context THIS HTML came from static navbar example of Bootstrap v3.3.7

actualy the idea is placing <div id="navbar" class="navbar-collapse collapse"> in row below <div class="navbar-header"> with floating and width it 100% of its space, then pulling up <ul class="nav navbar-nav navbar-right"> with margin-top: -50px;

With that media query we would sure it behave right in moblie device.

HTML

<div class="container-fluid">
  <div class="navbar-header">
    <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Logo/Brand</a>
  </div>
  <div id="navbar" class="navbar-collapse collapse">
    <ul class="nav navbar-nav">
      <li><a href="#">LinkA</a></li>
      <li><a href="#">LinkB</a></li>
      <li><a href="#">LinkC</a></li>
      <li><a href="#">LinkD</a></li>
      <li><a href="#">LinkE</a></li>
    </ul>
    <ul class="nav navbar-nav navbar-right">
      <li><a href="#">Link1</a></li>
      <li><a href="#">Link2</a></li>
      <li><a href="#">Link3</a></li>
    </ul>
  </div><!--/.nav-collapse -->
</div>

CSS

.navbar-collapse {
    float: left;
    width: 100%;
    clear: both;
}

@media (min-width: 768px) {
    .navbar-right {
        margin-top: -50px;
    }
}

JUST Let me know if it worked or not.
