Question

我目前正在尝试实现一个水平css下拉菜单，其中包含一个水平的子菜单。我已经尽力而为，直到初学者为止。我所能得到的只是默认的垂直下拉子菜单。

这是我的HTML代码：

<div class="dropdown">
    <button id="btn-icon">
        <i id="img-primary" class="fa fa-sitemap fa-2x"></i>
    </button>
    <ul class="dropdown-menu">
        <li><a href={% url 'acttemplate:listAll' %}>template</a></li>
        <li><a href={% url 'mission:create' userName %}>new</a></li>
    </ul>
</div>

CSS：

.dropdown {
        position: relative;
        display: inline-block;
    }

    .dropdown .dropdown-menu {
        position: absolute;
        top: 100%;
        display: none;
        margin: 0px;
        list-style: none;
        padding: 0px;
    }

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

    .dropdown .dropdown-menu ul li {
        display: inline;
    }

    .dropdown button {
        color: #FF6223;
        background-color: #FFFFFF;
        border: 1px solid #B3B3B3;
        margin: 0px;
        font-size: 16px;
    }

    .dropdown a {
        display: block;
        padding: 0.2em 0.8em;
        text-decoration: none;
        background: #FFFFFF;
        border: 1px solid #B3B3B3;
        color: #333333;
    }

    .dropdown a:hover {
        background: #BBBBBB;
    }

    #img-primary {
        color: #347EFF;
        max-height: 20px;
        max-width: 28px;
        margin: 5px;
        margin-left: 50px;
    }

    #img-primary:hover {
        color: #000000;
        max-height: 20px;
        max-width: 28px;
        margin: 5px;
        margin-left: 50px;
    }

    #btn-icon {
        color: #000000;
        background-color: #FFFFFF;
        border: 1px solid #FFFFFF;
        border-radius: 5px;
        cursor: pointer;
    }
