A dropdown menu who have dropdown's inside (Bootstrap-navbar) for tablet

提问by toshiro92

I tried to make a navbar with a dropdown menu inside, but in this, i wan't a dropdown menu inside. But when i click on it, the menu close. I wan't to block this function who when i click on it disapears, because i think it's because of that it cannot works. I saw a thing about stopPropagation on https://github.com/twitter/bootstrap/pull/3383but i don't know where i can declare this, and it isn't a formular.

我试图制作一个带有下拉菜单的导航栏，但在这里，我不想在里面有一个下拉菜单。但是当我点击它时，菜单关闭。我不想阻止这个功能，当我点击它时它会消失，因为我认为这是因为它无法工作。我在https://github.com/twitter/bootstrap/pull/3383上看到了一个关于 stopPropagation 的事情，但我不知道我可以在哪里声明它，它不是一个公式。

EDIT : I can't use li class="dropdown-submenu" because when you are on a mobile or a tablet, the menu close when you touch a link in it.

编辑：我不能使用 li class="dropdown-submenu" 因为当您使用手机或平板电脑时，当您触摸其中的链接时菜单会关闭。

I found another solution. I added that after my code :

我找到了另一个解决方案。我在我的代码之后补充说：

<script type="text/javascript"> 
$('.dropdown-menu').click(function(event){
    event.stopPropagation();
});
</script>

Dropdown can't works with this solution, so i used "dropdown-submenu" to fix that (Thanks @Schmalzy for that). So when i touch a link, the submenu open. the submenu can't works normally on a tablet without the code above.

Dropdown 无法使用此解决方案，因此我使用“下拉子菜单”来解决该问题（感谢 @Schmalzy）。因此，当我触摸链接时，子菜单会打开。如果没有上面的代码，子菜单将无法在平板电脑上正常工作。

您可以使用 bootstrap3 的响应式下拉菜单。

      <a href="./" class="navbar-brand">Bootstrap</a>
