html - 悬停时的Bootstrap下拉菜单(带有Creative-Tim图标Navbar)

这与普通的Bootstrap导航栏不同，它是在（http://www.creative-tim.com/live/navbar-with-icons）上找到的Bootstrap的Creative Tim图标导航栏。将鼠标悬停在下拉导航栏上时，我有些麻烦。我尝试使用...

.dropdown:hover .dropdown-menu {
display: block;
}

但没有喜悦。我怀疑创作者Tim navbar妨碍了某些事情。

这是我的HTML：

  <nav class="navscroll navbar navbar-light" style="background-color: #ecf1f0; color: #fff;" role="navigation">
    <div class="container">
    <div class="navbar-header">
    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#mynav">
        <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
  </div>
  <div class="collapse navbar-collapse" id="mynav">
    <ul class="nav navbar-nav" id="scroll">
        <li>
        <a href="#">
            <i class="fa fa-home" aria-hidden="true">
            </i>
            <p>Home</p>
        </a>
      </li>
      <li>
          <a href="#">
              <i class="fa fa-users" aria-hidden="true">
              </i>
              <p>About Us</p>
          </a>
      </li>
      <li>

        <li class="dropdown">
    <a href="#" class="dropdown-toggle" data-toggle="dropdown"><i class="fa fa-cube" aria-hidden="true">
    </i><p>Products</p></a>
    <ul class="dropdown-menu multi-column columns-3">

      </li>

        <li class="col-sm-4">
          <ul class="multi-column-dropdown" style="font-size:17px;">

            <li><a href="#process">Tube Wall</a></li>
            <li><a href="#process">Alu Wall</a></li>

          </ul>
        </li>
        <li class="col-sm-4">
          <ul class="multi-column-dropdown" style="font-size:17px;">

            <li><a href="#process">Wall Frames</a></li>

          </ul>
        </li>


    </ul>
</li>


      </li>
      <li>
        <a href="#">
            <i class="fa fa-shopping-cart" aria-hidden="true">
            </i>
            <p>Shop</p>

      <li>
        <a href="#">

            <p>Downloads</p>

      <li>
        <a href="#">

        </a>
      </li>
    </ul>


 </div>
</nav>

这是我的Navbar下拉菜单的CSS

.navbar-nav > li > .dropdown-menu{
    display: block;
    padding: 0;
    z-index: 9000;
    position: absolute;
    -webkit-border-radius: 0px !important;
    box-shadow: 1px 2px 3px rgba(0, 0, 0, 0.125);
    border-radius: 0px;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    opacity: 0;
    -ms-filter: "alpha(opacity=0)";
    -webkit-filter: alpha(opacity=0);
    -moz-filter: alpha(opacity=0);
    -ms-filter: alpha(opacity=0);
    -o-filter: alpha(opacity=0);
    filter: alpha(opacity=0);
    -webkit-transform: scale(0);
    -moz-transform: scale(0);
    -o-transform: scale(0);
    -ms-transform: scale(0);
    transform: scale(0);
    -webkit-transition: all 300ms cubic-bezier(0.34, 1.61, 0.7, 1);
    -moz-transition: all 300ms cubic-bezier(0.34, 1.61, 0.7, 1);
    -o-transition: all 300ms cubic-bezier(0.34, 1.61, 0.7, 1);
    -ms-transition: all 300ms cubic-bezier(0.34, 1.61, 0.7, 1);
    transition: all 300ms cubic-bezier(0.34, 1.61, 0.7, 1);
}

.navbar-nav > li.open > .dropdown-menu{
    -webkit-transform-origin: 29px -50px;
    -moz-transform-origin: 29px -50px;
    -o-transform-origin: 29px -50px;
    -ms-transform-origin: 29px -50px;
    transform-origin: 29px -50px;
    -webkit-transform: scale(1);
    -moz-transform: scale(1);
    -o-transform: scale(1);
    -ms-transform: scale(1);
    transform: scale(1);
    opacity: 1;
    -ms-filter: none;
    -webkit-filter: none;
    -moz-filter: none;
    -ms-filter: none;
    -o-filter: none;
    filter: none;
}

最佳答案

网站创意总监Tim用Java打开类。但是为您尝试：

更改此：

.navbar-nav > li.open > .dropdown-menu{
   -webkit-transform-origin: 29px -50px;
   -moz-transform-origin: 29px -50px;
   -o-transform-origin: 29px -50px;
   -ms-transform-origin: 29px -50px;
   transform-origin: 29px -50px;
   -webkit-transform: scale(1);
   -moz-transform: scale(1);
   -o-transform: scale(1);
   -ms-transform: scale(1);
   transform: scale(1);
   opacity: 1;
   -ms-filter: none;
   -webkit-filter: none;
   -moz-filter: none;
   -ms-filter: none;
   -o-filter: none;
   filter: none;
}

对此：

.navbar-nav > li:hover> .dropdown-menu{
   -webkit-transform-origin: 29px -50px;
   -moz-transform-origin: 29px -50px;
   -o-transform-origin: 29px -50px;
   -ms-transform-origin: 29px -50px;
   transform-origin: 29px -50px;
   -webkit-transform: scale(1);
   -moz-transform: scale(1);
   -o-transform: scale(1);
   -ms-transform: scale(1);
   transform: scale(1);
   opacity: 1;
   -ms-filter: none;
   -webkit-filter: none;
   -moz-filter: none;
   -ms-filter: none;
   -o-filter: none;
   filter: none;
}

将li.open更改为li：hover
