Question

我正在学习CSS并且我创建了一个垂直菜单，将鼠标悬停在第一个菜单项上，显示子菜单。但我的问题是，只要我将鼠标移动到子菜单，它就会消失。我如何才能使它保持在那里直到我点击其中一个子菜单项？请帮忙。

已经搜索了很多例子但没有类似的例子。我是css的新手，我不确定我的方法是否适合此菜单设置要求。请指教。

的CSS： .navLeft { 宽度：25％; margin-top：0％; 顶部：汽车; 显示：内联; list-style-type：none; margin-left：5％; 位置：相对; z-index：0; / * [disabled] clear：none; * / }

.navLeft ul li {
    list-style-type: none;
    width: 6em;
    height: 2em;
    /* [disabled]list-style-position: inside; */
    color: #F14E23;
    text-align: center;
    background-color: #FFFFFF;
    border: 0.5em solid #000000;
    margin-bottom: -0.5em;
    font-family: alfa-slab-one;
    font-style: normal;
    font-weight: 400;
    padding-top: 2em;
    top: auto;
    vertical-align: middle;
    padding-bottom: 2em;
    -webkit-transition: all 0.1s linear 0s;
    -o-transition: all 0.1s linear 0s;
    transition: all 0.1s linear 0s;
    position: relative;
    margin-left: -0.5em;
}

.navLeft ul li:hover {
    background-color: #F14E23;
    color: #FFFFFF;
    list-style-type: none;
    position: relative;
}
.navLeft ul .about {
    float: left;
    -webkit-transition: all .1s linear 0s;
    -o-transition: all .1s linear 0s;
    transition: all .1s linear 0s;
}
.navLeft ul ul li
 {
    float: left;
}
.navLeft ul .projects {
    clear: left;
}

.navLeft ul ul {
    display: none;
}

.navLeft ul .about:hover  ul{
    display: block;
}

和列表结构检查是问题Proper way to make HTML nested list?
