How to highlight a current menu item?

I suggest using a directive on a link.

But its not perfect yet. Watch out for the hashbangs ;)

Here is the javascript for directive:

angular.module('link', []).
  directive('activeLink', ['$location', function (location) {
    return {
      restrict: 'A',
      link: function(scope, element, attrs, controller) {
        var clazz = attrs.activeLink;
        var path = attrs.href;
        path = path.substring(1); //hack because path does not return including hashbang
        scope.location = location;
        scope.$watch('location.path()', function (newPath) {
          if (path === newPath) {
            element.addClass(clazz);
          } else {
            element.removeClass(clazz);
          }
        });
      }
    };
  }]);

and here is how it would be used in html:

<div ng-app="link">
  <a href="#/one" active-link="active">One</a>
  <a href="#/two" active-link="active">One</a>
  <a href="#" active-link="active">home</a>
</div>

afterwards styling with css:

.active { color: red; }

on view

<a ng-class="getClass('/tasks')" href="/tasks">Tasks</a>

on controller

$scope.getClass = function (path) {
  return ($location.path().substr(0, path.length) === path) ? 'active' : '';
}

With this the tasks link will have the active class in any url that starts with '/tasks'(e.g. '/tasks/1/reports')
