折叠侧面板

Question

在较小的屏幕上查看时如何折叠侧面板，以便“panel-header”成为切换按钮。 I.e而不是汉堡按钮，获得“过滤学生”按钮，这将扩展“面板体”。

<div class="panel">
  <div class="panel-header">
     <h3 class="panel-title">Filter Students</h3>
  </div>
  <div class="panel-body">
    <div class="search">
        <h3>SEARCH KEYWORD</h3>
        <input type="text" class="search-box" placeholder="Search" />
  </div>
 <div class="filter-categories">
     <ul class="filter">
       <li>Graphic Design</li>
        <li>Online Marketing</li>
        <li>Video Commercials</li>
        <li>Technology</li>
        <li>Photography</li>
        <li>Translation</li>
    </ul>
</div>                  
</div>
</div>

以下是如何使用jQuery toggleClass执行此操作的示例。当视口缩小到768px以下时，侧边栏会隐藏，并且可以在点击较大的视口时隐藏（如果需要，可以禁用此选项）。

$("#menu-toggle").click(function(e) {
  e.preventDefault();
  $("#wrapper").toggleClass("toggled");
});

body,
html {
  height: 100%;
  overflow: hidden;
}
#wrapper {
  padding-left: 0;
  -webkit-transition: all 0.5s ease;
  -moz-transition: all 0.5s ease;
  -o-transition: all 0.5s ease;
  transition: all 0.5s ease;
}
#wrapper.toggled {
  padding-left: 250px;
}
#sidebar-wrapper {
  z-index: 1000;
  position: fixed;
  left: 250px;
  width: 0;
  height: 100%;
  margin-left: -250px;
  overflow-y: auto;
  overflow-x: hidden;
  background: #DB1849;
  -webkit-transition: all 0.5s ease;
  -moz-transition: all 0.5s ease;
  -o-transition: all 0.5s ease;
  transition: all 0.5s ease;
}
#wrapper.toggled #sidebar-wrapper {
  width: 250px;
}
#page-content-wrapper {
  width: 100%;
  position: absolute;
  padding: 15px;
}
#wrapper.toggled #page-content-wrapper {
  position: absolute;
  margin-right: -250px;
}
.btn-default#menu-toggle,
.btn-default#menu-toggle:hover,
.btn-default#menu-toggle:focus {
  border: none;
  outline: none;
  box-shadow: none;
  background: none;
  color: #DB1849;
}
