you can easily remove tabs by altering scope, http://plnkr.co/edit/AKlmUaRkaYWjOYnPRnWF
$scope.remove = function() {
$scope.tabs.splice($scope.tabs.activeTab,1);
}
These tabs are problably created with templates from the tabs directive, so I suggest using css positioning the element outside the bs-tabs div to get the effect you want
