HTML5 / CSS - 展开横向菜单

Question

我花了大约 1 天的时间来解决这个问题，但我没有得到任何结果。我需要创建一个菜单，其中包含一些 link 折叠的菜单，当我将鼠标悬停在父级 <li> 上时，它们会出现在它旁边。类似于下拉菜单，但在水平方向。

编辑： *"Uscite" 和 "Guide" link 出现在 "Blog" 附近，其他 link 出现鼠标移出需要右滑回来*

我尝试使用 display: none 和 display: block，这似乎可行，但使用此方法我无法应用任何类型的过渡，因此结果有点难看。我也尝试使用 google，但找到的每个线程都对我没有帮助。

谁能帮帮我？在这个 link 你可以找到我的代码：Codepen Link

.mpx_nav {
    background-color: rgba(98, 98, 98, 1);
    width: 100%;
    height: 40px;
}
.nav_menu a{
    display: inline-block;
    padding: 0 1em;
    text-decoration: none;
    list-style: none;
    color: #eee;

    -webkit-transition: all .3s ease-in-out;
    -moz-transition: all .3s ease-in-out;
    -o-transition: all .3s ease-in-out;
    transition: all .3s ease-in-out;
}
.nav_menu a:hover {
    background-color: #eee;
    color: #333;
    font-weight: 700;

.dropdown {
    position: relative;

添加white-space:nowrap使所有链接在一行中。看看下面的片段。
