twitter-bootstrap – 在移动设备上隐藏菜单中的一项

我正在使用Bootstrap来构建菜单.当为小屏幕调整页面大小时,我会获得汉堡包图标,并显示菜单中的所有项目.有没有办法隐藏该菜单中的一个项目？我不希望我的购物车出现在汉堡包下面.我自己可以写一些jQuery代码来做到这一点,但我想知道Bootstrap是否已经有办法做到这一点？

解决方法

如果您使用 Bootstrap responsive utility classes hidden-*课程,这很容易.在您的情况下,将hidden-xs添加到按钮.

<button type="button" class="navbar-toggle btn-lg hidden-xs">
