Bootstrap左侧可折叠导航菜单

Question

我试图找到一个好的模板或部分代码来应用我在本网站上找到的相同菜单：

http://progressive.com/

我需要从左侧和屏幕的其余部分显示的菜单稍微变暗，就像我找到的网站一样。

是否有一种简单的方法来应用执行此操作的引导程序模板？或者也许可以方便地从头开始编写导航栏部分？

谢谢，

Answer 1

为什么不在侧边菜单中使用jQuery插件？

http://www.berriart.com/sidr/将满足您的需求。

让屏幕的其余部分变暗也是一个简单的jQuery技巧。以下SO答案将帮助您解决这个问题。

Answer 2

我刚刚开始做类似的事情。我没有使用叠加来实现模态效果，但这不应该难以实现。看看这个例子，我相信你会明白这个想法。可能是一个很好的起点，尽管可以通过许多不同的方式实现同​​样的目标。

var $navbarToggle = $('.navbar-toggle'),
    $flyoutContainer = $('.navbar-flyout-container'),
    $flyoutDropdownItem = $('.flyout-dropdown-item');

function openFlyout (evt) {
  $(this).toggleClass('navbar-toggle-open');
  $flyoutContainer.toggleClass('navbar-flyout-open');
}

function openDropdownNavList (evt) {
  $(this).find('.flyout-dropdown-container').toggleClass('flyout-dropdown-open');    
}

$navbarToggle.on('click', openFlyout);

$flyoutDropdownItem.on('click', openDropdownNavList);

＆＃13;

$(document).ready(function() {
  var trigger = $('.hamburger'),
    overlay = $('.overlay'),
    isClosed = false;

  trigger.click(function() {
    hamburger_cross();
  });

  function hamburger_cross() {

    if (isClosed == true) {
      overlay.hide();
      trigger.removeClass('is-open');
      trigger.addClass('is-closed');
      isClosed = false;
    } else {
      overlay.show();
      trigger.removeClass('is-closed');
      trigger.addClass('is-open');
      isClosed = true;
    }
  }

  $('[data-toggle="offcanvas"]').click(function() {
    $('#wrapper').toggleClass('toggled');
