Bootstrap navbar with two rows
提问by johna
I am wanting to have a Bootstrap 3 navbar that has two rows with navigation elements, and with navbar-brand spanning both rows. On SM+ screen sizes both rows are visible. On XS screen sizes the second row collapses and shows the icon-bar to open.
我想要一个 Bootstrap 3 导航栏，它有两行带有导航元素，并且导航栏品牌跨越两行。在 SM+ 屏幕尺寸上，两行都可见。在 XS 屏幕尺寸上，第二行折叠并显示要打开的图标栏。

How could this be done with the navbar?
这怎么能用导航栏完成？
回答by vanburen
You can essentially use two navbars and then use position: absolutefor your image. You could potentially use the grid but your collapse menu won't be full-width on mobile most likely then.
您基本上可以使用两个导航栏，然后position: absolute用于您的图像。您可能会使用网格，但那时您的折叠菜单在移动设备上很可能不会是全宽的。
Working Example:
工作示例：
.navbar-inverse.nav-upper {
height: 50px;
}
.navbar-inverse.nav-upper ul {
float: right;
display: table;
}
.navbar-inverse.nav-upper .navbar-upper > li {
display: table-cell;
font-size: 14px;
}
.navbar-inverse.nav-upper .navbar-upper > li > a {
color: #777;
}
@media (min-width: 768px) {
.navbar.navbar-lower .navbar-nav {
margin-left: 100px;
}
}
.navbar-logo {
background-image: url('https://lh3.googleusercontent.com/-tw5LsU4Fg28/Umo6BBcoCnI/AAAAAAAAmjE/1iqULsem06E/w896-h896/heisencat.png');
width: 90px;
height: 90px;
background-size: cover;
background-position: center center;
background-repeat: no-repeat;
position: absolute;
top: 5px;
left: 15px;
z-index: 1051;

Try this. On SM+ screen sizes both rows are visible. On XS screen sizes the second row collapses and shows the icon-bar to open at right side.
试试这个。在 SM+ 屏幕尺寸上，两行都可见。在 XS 屏幕尺寸上，第二行折叠并显示图标栏以在右侧打开。
