title: Angular UI Bootstrap - Collapsing tab content
body: <p>Using the AngularJS UI Directives for bootstrap, is there any way to collapse the tab content using the  tag? </p>
  
  <p>I have several tabs/pills with content, which will start collapsed (hidden). When any of the tabs is activated, the tab content should collapse open, and stay open until a close button is clicked, which will close the collapsable section.</p>
  
  <p>In the controller, I set $scope.isCollapsed to true. Each of the tabs have the ng-click which calls openCollapse(), which sets isCollapsed to false. If I add the collapse="isCollapsed" directive right to the  tag, then the tabs disappear too, not just the content.</p>
  
  <p>How can I fix this?</p>
