html - 悬停时下拉菜单项消失

Question

我有以下下拉列表:

CSS:

.third-menu{
    position: relative;
    top: -50px!important;
}


.dropdown-submenu {
    border-bottom: 1px solid #ccc;
}


#mn-wrapper {
  display: block;
  width: 100%;
  position: absolute;
    height: 30px;


}
.mn-sidebar {
  margin-left: 40px;
  display: block;
  position: relative;
  vertical-align: middle;
  padding-bottom: 1px;
    background: #333333;
    width: 250px;
    z-index: 2;
}
#mn-cont {
  display: block;
    vertical-align: top;     
    position: relative;
    padding: 10;
}
.container {
    margin-right: auto;
}
.cnt-mcont {
  background-color: #F6F6F6;
  color: inherit;
  font-size: 13px;
  font-weight: 200;
  line-height: 21px;
  padding: 15px 30px 30px 30px;
  margin-top: 0;
    height: 101vh;
}
.mn-sidebar .mn-toggle {
  display: none;
  padding: 10px 0;
  text-align: center;
    cursor: pointer;
}
.mn-vnavigation {
  margin: 0 0 0 0;
  padding: 0;
  border-top: 2px solid #CCFFFF;
    border-bottom: 1px solid #CCFFFF;
border-left: 5px solid #CCFFFF;
border-right: 5px solid #CCFFFF;

}
.mn-vnavigation li a {
  border-top: 2px solid #CCFFFF;
  border-bottom: 1px solid #CCFFFF;
  display: block;
  padding: 14px 18px 13px 15px;
  color: #fff;
  text-decoration: none;
  font-size: 12px;
  font-weight: 300;
  text-shadow: 1px 1px 0 rgba(0, 0, 0, 0.3);
    white-space: nowrap;
}
.dropdown-submenu >
.dropdown-menu {
    top: 0;
  left: 100%;
  margin-top: -6px;
  margin-left: -1px;
  /*height: 590px; */
  width: 300px;
  background: #333333;
}
.dropdown-submenu:hover > 
.dropdown-menu {

    display: list-item;
}

.dropdown-submenu > a:after {

    display: list-item;
    content: " ";
    float: right;
    width: 0;
    height: 0;
    border-color: transparent;
    border-style: solid;
    border-width: 5px 0 5px 5px;
    border-left-color: #ccc;
    margin-top: 5px;
    margin-right: -10px;
}
.dropdown-submenu:hover > a:after {
    border-left-color: #fff;
}
.dropdown-submenu.pull-left {
    float: none;
}
.dropdown-submenu.pull-left > .dropdown-menu {
    left: -100%;
    margin-left: 10px;
    -webkit-border-radius: 6px 0 6px 6px;
    -moz-border-radius: 6px 0 6px 6px;
    border-radius: 6px 0 6px 6px;
}
ul {
    list-style: none;
}
ul.dropdown-menu.parent {
  margin-top: -1px;
}

fiddle 中的 Javascript。

这是 jsfiddle:

现在，当我将鼠标悬停在 Central Compliance 上的元素上时，其下方的其余元素(控制室、财富应用程序等)就会消失。如果我越过控制室，Orchestria 就会出现在空白处。

如何解决这个问题？

将此添加到您的 CSS 中:

.third-menu{
    position: absolute;
    right:0;
    top:0;
}


.dropdown-submenu {
    border-bottom: 1px solid #ccc;
    position:relative;
}
