Bootstrap 3 Off-Canvas Sidebar Menu Like Facebook's
提问by Allen B.
I'm using some examples of Bootstrap 3 for an off-canvas sidebar menu when it gets to mobile which can be seen here: http://jsfiddle.net/AllenDB/9aAjJ/
我正在使用 Bootstrap 3 的一些示例作为移动设备时的画布侧边栏菜单，可以在此处看到：http: //jsfiddle.net/AllenDB/9aAjJ/
How would I go about getting the off-canvas menu adjusted to act like Facebook's search/friends online off-canvas menu to where it always starts at the top of the menu and you can only scroll within? As with my example the navbar is fixed so one may toggle the sidebar menu. But when you have scrolled down the actual page and toggle the menu you have to scroll back up to see the links. I would like to see how can I get this adjusted to where the menu starts at the top and pushes the content and fixed navbar to the side while being able to scroll within the menu and not the content?
我将如何调整画布外菜单，使其像 Facebook 的搜索/好友在线画布外菜单一样始终位于菜单顶部且您只能在其中滚动？与我的示例一样，导航栏是固定的，因此可以切换侧边栏菜单。但是当您向下滚动实际页面并切换菜单时，您必须向上滚动才能看到链接。我想看看如何将其调整到菜单从顶部开始的位置并将内容和固定导航栏推到一边，同时能够在菜单中滚动而不是内容？
The CSS:
CSS：
html,
body { overflow-x: hidden; }
body { padding-top: 70px;}
.navbar { color: #FFF; }
footer { padding: 30px 0; }
/*
* Off Canvas
* --------------------------------------------------
*/
@media screen and (max-width: 767px) {
.row-offcanvas { position: relative; -webkit-transition: all 0.25s ease-out; -moz-transition: all 0.25s ease-out; transition: all 0.25s ease-out; }
.row-offcanvas-right
.sidebar-offcanvas { right: -50%; /* 6 columns */ }
.row-offcanvas-left
.sidebar-offcanvas { left: -50%; /* 6 columns */ }
.row-offcanvas-right.active { right: 50%; /* 6 columns */ }
.row-offcanvas-left.active { left: 50%; /* 6 columns */ }
.sidebar-offcanvas { position: absolute; top: 0; width: 50%; /* 6 columns */ }
}

If I understand the question, I think you're looking to have the sidebar scroll independently of the main content.
如果我理解这个问题，我认为您希望侧边栏独立于主要内容滚动。
