Bootstrap 3: Fixed Right Sidebar

Question

I using one of the Bootstrap 3 example to build a sidebar. It works fine. But how can fix its position like navigation bar so that I won't loose it while scrolling down.
I tried adding .uploadSideBar class to <div class="col-xs-6 col-sm-3 sidebar-offcanvas sidebar-nav-fixed uploadSideBar" like this

.uploadSideBar {
    margin-top:117px;
    postion:fixed
}

But it did not work.

Answer 1

I think you're using the wrong selector. Use this one instead, I've tested it on the link you gave and it works:

.well.sidebar-nav {
position: fixed;
}
