Question

所以我遇到了一个非常奇怪的兼容性问题，我使用了一个带有bootsrap 4.0 beta的sidenav菜单的下拉列表，它在Firefox上运行得非常好，但在Chrome上我有一个问题：

基本上当页面加载时，如果你单击下拉按钮它会上升，好像它有一个看不见的负边距顶部，但是当你滚动页面一点点，然后你重新点击它，下拉列表将会正常显示....

以下是使用

的代码示例

Answer 1

对于下拉项目使用html标签元素而不是ul和li元素。

 <div class="dropdown-menu" aria-labelledby="frontend">
<a class="dropdown-item" href="#">HTML</a>
<a class="dropdown-item" href="#">CSS</a>
<a class="dropdown-item" href="#">JS</a>
</div>
