twitter-bootstrap - Bootstrap 3 和菜单

Question

我想将mmenu实现到 Bootstrap 3，但我被卡住了。我想要顶部导航，并且在折叠时我希望它更改为左侧滑动菜单。在此先感谢您的帮助。

编辑：我做了这个：https ://github.com/purgeru/mmenu-Bootstrap-3 。如果有人想贡献。

Answer 1

这可以在不mmenu添加一些 CSS 的情况下完成。

我建议您创建 2 个不同的导航：

• A .navbar.navbar-fixed-topfor -sm,-md和-lg设备
• A.sidebar-offcanvas用于-xs设备

有关基于Offcanvas 模板的工作示例，请参阅此 Bootply。

评论示例：

<!-- Classic nav -->
<div class="navbar navbar-fixed-top navbar-inverse" role="navigation">
  <div class="container">
    <div class="navbar-header">
      <!-- We change data-toggle to "offcanvas" -->
      <button type="button" class="navbar-toggle" data-toggle="offcanvas">
        <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="#">Project name</a>
    </div>
    <div class="collapse navbar-collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#about">About</a></li>
        <li><a href="#contact">Contact</a></li>
      </ul>
    </div>
  </div>
</div>

<div class="container">

  <!-- You can use .row-offcanvas-left or .row-offcanvas-right -->
  <div class="row row-offcanvas row-offcanvas-left">

    <!-- Here is the offcanvas nav, with .visible-xs class -->
    <div class="col-xs-6 visible-xs sidebar-offcanvas" id="sidebar" role="navigation">
      <div class="list-group">
        <a href="#" class="list-group-item active">Home</a>
        <a href="#" class="list-group-item">About</a>
        <a href="#" class="list-group-item">Contact</a>
      </div>
    </div>

    <div class="col-12">
      Content
    </div>

  </div>

</div>

你需要一些 CSS ：

/*
 * Off Canvas
 * --------------------------------------------------
 */
@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: -50%; }
  .row-offcanvas-right .sidebar-offcanvas .list-group { padding-right: 10px; }
  .row-offcanvas-right.active { right: 50%; }

  .row-offcanvas-left .sidebar-offcanvas { left: -50%; }
  .row-offcanvas-left .sidebar-offcanvas .list-group { padding-left: 10px; }
  .row-offcanvas-left.active { left: 50%; }

  .sidebar-offcanvas {
    position: absolute;
    top: 0;
    width: 50%; /* 6 columns */
  }
}

还有几行 JS ：

$(document).ready(function() {
  $('[data-toggle=offcanvas]').click(function() {
    $('.row-offcanvas').toggleClass('active');
  });
});
