html - Bootstrap 3: Fixed Right Sidebar -

-

i using 1 of bootstrap 3 example build sidebar. works fine. how can fix position navigation bar won't loose while scrolling down.
tried adding .uploadsidebar class <div class="col-xs-6 col-sm-3 sidebar-offcanvas sidebar-nav-fixed uploadsidebar" this

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

but did not work.

i think you're using wrong selector. use 1 instead, i've tested on link gave , works:

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