Creating a dynamic sidebar based on roles in AngularJS

I'm looking to create a dynamic sidebar based on the user's role, which is stored in $rootScope.login. However, I'm unsure of how to integrate it into template.js.

Below is my JavaScript code and I'm still relatively new to AngularJS.

template.js

$templateCache.put('template/sidebar-left.html',
        "<div class=\"sidebar-inner c-overflow\"><div class=\"profile-menu\"><a href=\"\" toggle-submenu><div class=\"profile-pic\"><img src=\"img/profile-pics/1.jpg\" alt=\"\"></div><div class=\"profile-info\">Malinda Hollaway <i class=\"zmdi zmdi-caret-down\"></i></div></a><ul class=\"main-menu\"><li><a data-ui-sref=\"pages.profile.profile-about\" data-ng-click=\"mactrl.sidebarStat($event)\"><i class=\"zmdi zmdi-account\"></i> View Profile</a></li><li><a href=\"\"><i class=\"zmdi zmdi-input-antenna\"></i> Privacy Settings</a></li><li><a href=\"\"><i class=\"zmdi zmdi-settings\"></i> Settings</a></li><li><a href=\"\"><i class=\"zmdi zmdi-time-restore\"></i> Logout</a></li></ul></div><ul class=\"main-menu\"><li data-ui-sref-active=\"active\"><a data-ui-sref=\"home\" data-ng-click=\"mactrl.sidebarStat($event)\"><i class=\"zmdi zmdi-home\"></i> Dashboard</a></li><li data-ui-sref-active=\"active\"><a data-ui-sref=\"timeline\" data-ng-click=\"mactrl.sidebarStat($event)\"><i class=\"zmdi zmdi-layers\"></i>Timeline</a></li>...");

controller.js

this.loginF = function(user) {

    $http.post("data/login.php", user).then(function(userData) {

        $rootScope.login = userData.data
        if( $rootScope.login == "failed" ) {
            alert(JSON.stringify($rootScope.login))
        } else {
            window.location.assign("home.html");
        }
    })
}

To implement this functionality, consider creating a directive like the following:

app.directive("userMenu", function() {
    return {
        restrict: "AE",
        scope: {
            user: "="
        },
        templateUrl: "template/sidebar-left.html",
        link: function($scope, $elem, $attrs) {
            $scope.hasRole = function(role) {
                if (!$scope.user) {
                    return false;
                }

                // If the user data model is like { roles: ["admin", "editor"] }
                return $scope.user.roles.indexOf(role) > -1;
            }
        }
    }
});

You can then use this directive in your sidebar-left template as shown below:

<div>
    <ul class="menu">
        <li ng-if="hasRole('admin')">
            <a href="#">This will only be displayed if the user has the 'admin' role</a>
        </li>
        <li>
            <a href="#">This will always show, regardless of the user's role</a>
        </li>
    </ul>
</div>

Finally, include it in your HTML markup like this:

<div user-menu user="$root.login"></div>
