Bootstrap - Can't click dropdown child menu items on mobile and first click not triggering nav-collapse
提问by Tom Hartman
I've run into two issues with dropdown menu items on mobile devices. Specifically:
我在移动设备上遇到了下拉菜单项的两个问题。具体来说：
- My nav-collapse isn't shown on the first click of btn-navbar, but only on an iPhone.
- While I can toggle dropdowns, I can't click on any dropdown-menu items on mobile devices.
- 我的导航折叠不会在第一次点击 btn-navbar 时显示，而只会在 iPhone 上显示。
- 虽然我可以切换下拉菜单，但我无法点击移动设备上的任何下拉菜单项。
My page is valid on W3 Validator and I have added both the .nav-collapse and .collapse classes to my navbar. Plus everything works fine when resizing the browser window on my laptop.
我的页面在 W3 Validator 上有效，并且我已将 .nav-collapse 和 .collapse 类添加到我的导航栏。另外，在我的笔记本电脑上调整浏览器窗口大小时，一切正常。

Yes, I've seen this before and I saw the issue is on github as well. I don't remember exactly where I found this, but some guy was saying that it was an issue about setting those elements to position: absolute;and that re setting them to static would fix it.
是的，我以前见过这个，我在 github 上也看到了这个问题。我不记得我在哪里找到了这个，但有人说这是一个关于将这些元素position: absolute;设置为静态的问题，将它们重新设置为静态可以解决它。
So why don't you go ahead and try this on your custom CSS:
那么为什么不继续在您的自定义 CSS 上尝试这个：
CSS
CSS
.dropdown-backdrop {
position: static;
}
Let me know if we're on the same page and this solved your issue.
如果我们在同一页面上，请告诉我这解决了您的问题。
