Here is my HTML

            <div class="sidebar-nav">
                <div class="navbar navbar-default" role="navigation">
                    <div class="navbar-header">
                        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#committees-navbar">
                            <span class="sr-only"></span>
                            <span class="icon-bar"></span>
                            <span class="icon-bar"></span>
                            <span class="icon-bar"></span>
                        </button>
                        <span class="visible-xs navbar-brand">Committees</span>
                    </div>
                    <div id="committees-navbar" class="navbar-collapse collapse">
                        <ul class="nav navbar-nav nav-stacked" data-spy="affix" data-offset-top="250">
                            <li class="col-xs-12"><a ng-click="scrollTo('boardCommittee')">BOARD OF DIRECTORS</a></li>
                            <li class="col-xs-12"><a ng-click="scrollTo('madrasaCommittee')">MADRASATUL JAMALIYAH</a></li>
                            <li class="col-xs-12"><a ng-click="scrollTo('shababCommittee')">SHABAB</a></li>
                            <li class="col-xs-12"><a ng-click="scrollTo('bwaCommittee')">BURHANI WOMEN</a></li>
                            <li class="col-xs-12"><a ng-click="scrollTo('tncCommittee')">TAISEER UN NIKAH</a></li>
                            <li class="col-xs-12"><a ng-click="scrollTo('fmbCommittee')">FAIZUL MAWAIDUL BURHANIYAH</a></li>
                            <li class="col-xs-12"><a ng-click="scrollTo('websiteCommittee')">WEBSITE</a></li>
                            <li class="col-xs-12"><a ng-click="scrollTo('tadfeenCommittee')">TADFEEN</a></li>
                        </ul>
                    </div><!--/.nav-collapse -->
                </div>
            </div>

And this is my JS fix

$(function () {
   var resize = function () {
      var sidebarNav = $(".sidebar-nav");
      var sidebarNavAffix = $(".sidebar-nav .affix");
      if (sidebarNavAffix.length && (sidebarNavAffix.width() !== sidebarNav.width())) {
             sidebarNavAffix.width(sidebarNav.width());
      }
   }

   $(window).on({"scroll" : resize, "resize" : resize});
});

Answer 3

I had the same problem and fixed with this:

 $(window).resize(function () {
                $('#category-nav.affix').width($('#content').width());
            });

basically in an event of resize I calculate the content div's width and set the width of affixed element to that.
