基础5顶部栏下拉菜单随机不工作，然后工作后刷新页面

I have tried it using both "hover" and "clickable" and got the same random breakdowns. Any time it hasn't worked, simply refreshing the page has solved the problem, but this is still a problem for users that I would like to avoid. Any suggestions?I have a dropdown menu in my rails app (rails 4
