懸停時的Bootstrap下拉菜單（帶有Creative-Tim圖標Navbar）

Question

這與普通的Bootstrap導航欄不同，它是Bootstrap的Creative Tim圖標導航欄，位於（ http://www.creative-tim.com/live/navbar-with-icons ），我遇到了一些麻煩將我的下拉式導航欄懸停時打開。 我嘗試使用...

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

但沒有喜悅。 我懷疑創作者Tim navbar妨礙了某些事情。

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

          <li><a href="#process">Foam Cases</a></li>
        </ul>
      </li>

        <li class="col-sm-4">
          <ul class="multi-column-dropdown" style="font-size:17px;">
            <li><a href="#process" style="font-weight: bold">Image Walls</a></li>
            <li><a href="#process">Pop Up wall</a></li>
            <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">Outdoor / Flags</a></li>
            <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>
        </a>
      </li>
      <li>
        <a href="#">
            <i class="fa fa-download" aria-hidden="true">
            </i>
            <p>Downloads</p>
        </a>
      </li>
      <li>
        <a href="#">
            <i class="fa fa-newspaper-o" aria-hidden="true">
            </i>

      </li>
      <li>
        <a href="#">
          <i class="fa fa-phone" aria-hidden="true">
          </i>
          <p>Contact Us</p>
        </a>
      </li>
    </ul>


 </div>
</nav>

這是我的Navbar下拉菜單的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;
}

網站創意總監蒂姆（Tim）使用Java打開課程。 但是為您嘗試：

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;
}

對此：

.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;
}

將li.open更改為li：hover

Answer 2

這段代碼阻止了它

.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);
}

您要做的就是更改此：

.navbar-nav > .li.open > .dropdown-menu{
...
}

進入

.navbar-nav > .dropdown:hover > .dropdown-menu{
...
}
