html - 悬停时显示子菜单的垂直下拉菜单

Question

我想制作一个具有以下结构的垂直下拉菜单(对于每个“按钮”一个不同的“下拉”div)。我的想法是当我将鼠标悬停在“按钮”上时，“下拉菜单”出现具有相同大小的“按钮”(“下拉菜单”缩小到具有相同高度“subnav1”的“按钮”大小)或出现在“下拉菜单”的左侧(再次等同高度“subnav1”)。然而，问题是我无法使“按钮”上的“下拉菜单”display:block悬停，并且在第二种情况下，在选择“subnav1”时悬停“按钮” “元素。 HTML:

<div class="nav">
    <ul class="nav1">
        <li class="button"><div class="subnav">BUTTON1</div></li>
        <li class="button"><div class="subnav">BUTTON2</div></li>
        <li class="button"><div class="subnav">BUTTON3</div><li>
        <li class="button"><div class="subnav">BUTTON4</div></li>
        <li class="button"><div class="subnav">BUTTON5</div></li>
    </ul></div>
    <div class="dropdown">
        <A href="#" class="subnav1">SUBBUTTON1</a>
        <A href="#" class="subnav1">SUBBUTTON1</a>
        <A href="#" class="subnav1">SUBBUTTON1</a>
    </div>

CSS:

.nav {
    width: 180px;
    padding: 1vm;
    float:left;
    height:450px;
    position:relative;
    text-align:center;
    background-color:#a56d3b;
}
ul{
    list-style:none;
    margin: 0;
    padding: 0;
    text-align:right;
}
.nav a{
    text-decoration:none;

}
.subnav{
    font-weight:bold;
    text-align:center;
    color:#FCFBE3;
    font-family: 'PT Serif', serif;
    font-size:1.3em;
    display:block;
}
.button{
    border-bottom:1PX DOTTED #FFECBA;
    border-right:1PX DOTTED #FFECBA;
    height:90px;
    width:100%;
    padding:2em 0 0 0 ;
    cursor:pointer;
}
.button:last-child{
    border-bottom:0px;
}
.button:hover{
    background-color:rgba(0,0,0,0.5);
}
.dropdown{
    height:89px;
    float:left;
    width:auto;
    min-width:100px;
    text-align:center;
    margin:0 180px;
    position:absolute;
    cursor:pointer;
    border:1px solid black;

}

.subnav1{
    height:30px;
    width:180px;
    padding:5px 0;
    color:black;
    font-family: 'PT Serif', serif;
    font-size:1em;
    color:white;
    text-decoration:none;
    background-color:#D8A06E;
        DISPLAY:BLOCK;
}
.subnav1:hover{
    background-color:rgba(0,0,0,0.5);
}
.nav.nav1 .button:hover .dropdown{
    display:block;
}
