使用 Bootstrap 折叠侧边栏 [英] Collapsing Sidebar with Bootstrap

问题描述

我刚刚访问了这个页面 http://www.elmastudio.de/ 并想知道是否可以使用 Bootstrap 3 构建左侧边栏折叠.

I just visited this page http://www.elmastudio.de/ and wondered if it is possible to build the left sidebar collapse with Bootstrap 3.

从顶部折叠侧边栏的代码(仅限手机):

Code to collapse the sidebar from the top (phone only):

<button type="button" class="navbar-toggle sidebar-toggle" data-toggle="collapse" data-target=".sidebar-ex1-collapse">
    <span class="sr-only">Sidebar</span>
    <span class="glyphicon glyphicon-check"></span>
</button>

侧边栏本身有 hidden-xs 类.用下面的js去掉

Sidebar itself has the hidden-xs class. It is removed with the following js

$('.sidebar-toggle').click(function(){
     $('#sidebar').removeClass('hidden-xs');            
});

如果您单击该按钮，它会从顶部切换侧边栏.很高兴看到侧边栏的行为像上面显示的网站一样.任何帮助表示赞赏！

If you click the button it toggles the sidebar from the top. It be great to see the sidebar behave like the website above shows. Any help is appreciated!

基本上，您需要将布局包装在外部 div 中，并使用媒体查询在较小的屏幕上切换布局.

Basically you need to wrap the layout in an outer div, and use media queries to toggle the layout on smaller screens.

/* collapsed sidebar styles */
@media screen and (max-width: 767px) {
  .row-offcanvas {
    position: relative;
    -webkit-transition: all 0.25s ease-out;
    -moz-transition: all 0.25s ease-out;
    transition: all 0.25s ease-out;
  }
  .row-offcanvas-right
  .sidebar-offcanvas {
    right: -41.6%;
  }

  .row-offcanvas-left
  .sidebar-offcanvas {
    left: -41.6%;
  }
  .row-offcanvas-right.active {
    right: 41.6%;
  }
  .row-offcanvas-left.active {
    left: 41.6%;
  }
  .sidebar-offcanvas {
    position: absolute;
    top: 0;
    width: 41.6%;
  }
  #sidebar {
    padding-top:0;
  }
}
