Question

我目前正在开发一个向上垂直扩展的菜单栏。当我将溢出更改为可见而不是隐藏时，菜单会在正确的位置展开，但是整个菜单都是可见的，我不想发生这种情况。溢出：隐藏;菜单会扩展，但只有当您将鼠标悬停在我希望展开的部分展开的菜单上方时。有人可以帮忙吗？

.HomeBottomMenu {

    -webkit-font-smoothing:antialiased;
    text-align: center;
    text-align: justify;
    position: fixed;
    bottom: 6em;
    z-index:9999;
}

.HomeBottomMenu ul {

    list-style-type: none;
    margin: 0;
    padding: 0;
}

.HomeBottomMenu ul ul {

    height: 0px;
}

.HomeBottomMenu ul ul:hover {

     height:532px;  
    -webkit-transition: height 1s ease;
    -moz-transition: height 1s ease;
    -o-transition: height 1s ease;
    -ms-transition: height 1s ease;
    transition: height 1s ease;
}


.HomeBottomMenu ul li{

    line-height: 21px;
    min-width: 220px;
    text-align: center;/* Used to be left*/

    background: #f2f2f2;
    display: hidden;
    position: absolute;
    left: -0.01em;
    overflow: hidden;

}

.HomeBottomMenu ul li:hover .dropdown{

   /* Display the initial dropdown */
    display: block; 
    bottom: 100%;
    position: absolute;
    background: #939393;
    min-height: 50px;
}

.HomeBottomMenu ul li ul.dropdowndropdown {

    position: relative;
    height:100%;
    display:inline-block;
    bottom:100%;
}

.HomeBottomMenu ul li ul :hover .dropdowndropdown{

    position: relative;
    display:inline-block;
}

.HomeBottomMenu ul li ul.dropdowndropdown li{

    display: inline-block;
    /*Colour of level 1, level 2...*/
    background-color: rgba(0, 90, 235, 0.33);
    bottom: 100%;

}
.HomeBottomMenu ul li ul.dropdowndropdown li:hover{

   position: relative;
}

.HomeBottomMenu ul li ul.dropdowndropdown li a{

    color:#fff;
    font-size:16px;
    padding: 10px 10px;
