Mozilla FireFox悬停的工作方式与Chrome中的不同

Question

我有自定义下拉列表...大部分工作都是使用css完成的。通过添加删除ui-dropdown-expanded类

来打开/关闭此下拉列表

这是我的所有代码

＆＃13;

＆＃13;

$(document).on('click', '#ResponseFilter', function() {
  $(this).find('ul').toggleClass('ui-dropdown-expanded');
});

在摘录中它与jsFiddle中的有点不同（不知道原因，导致代码相同）

问题 - 在FF中尤其是下拉按钮和下拉列表之间存在一些空间，这会使下拉列表关闭，导致用户丢失:hover:

在图像上有用户可以看到下拉列表的poiners而不是......

这个问题是因为保证金，填充还是什么？ 感谢。

Answer 1

将下拉列表提高一点，将margin添加到类-1px;的现有边距，以解决我的问题。
