我在rails中构建一个下拉菜单。我的application.html.erb文件中有菜单。在它的正下方,我有<%= yield%>标记我的内容去哪里。当我的下拉菜单超出标题部分并进入部分区域时,它会被切断。我检查了溢出,没有人将它设置为“隐藏”。我不确定发生了什么。如果重要的话,父母正在浮动。 有人可以帮忙吗?
以下是该问题的图片:
这是CSS。我正在使用SASS进行媒体查询

这是我的application.html.erb文件:

这是我的show.html.erb。请注意它发生在每个视图中,而不是jsut这个,这让我相信问题在于application.html.erb
<section>
<div class="container_books_show">

<% end %>

听起来像是一个z索引问题。确保您的下拉列表具有比您想要在其下面的其他元素更高的z-index。
