How to add a navbar above navbar?

Hey guys,

so i'm trying to write (emphasis on trying) a custom plugin that will add a navbar above current navbar.
And honestly i'm lost.. my PHP skills are none but i do have some knowledge of programming.

I'd appreciate a lot every hint/direction of where to start.
I think i figured out that i have to use function Base_render_before and $Sender->smth->AddString('some html here')
where smth is something that i have no idea what.. a hook that i should use? appreciated :)

I'm using Vanilla 2.1 and Vanilla bootstrap theme (united).

    hgtonight hi and thanks!
    Yeah thats my backup plan (default.master.tpl) but not a very good one for me because my intention is to pull page titles and links from a database..
    And smartys php tag is deprecated now so.. any other ideas?

    EDIT - Please read the follow up to this post for corrected code.

    For dynamic content, I suggest you add a new asset, create a module that contains your logic, and then add this module to every page.

    1. Create a new asset in your /themes/bootstrap/views/default.master.tpl file using the smarty tag {asset name="AboveNavbar"}.
    2. Create a file in /themes/bootstrap/modules called class.dynamicnavbarmodule.php and paste in the following code:

      <?php if(!defined('APPLICATION')) exit();
       * Renders a dynamic navbar
      class DynamicNavbarModule extends Gdn_Module {
        public function __construct($Sender = '') {
          $this->Data('Menu', 'this is my sweet new navbar!');
        public function AssetTarget() {
          return 'AboveNavbar';
        public function ToString() {
          $Menu = $this->Data('Menu');
          if($Menu) {
            return $Menu;
    3. Add the module to every page with the following code in your /themes/bootstrap/class.bootstrapthemehooks.php file:

      class BootstrapThemeHooks implements Gdn_IPlugin {
        /** No setup required. */
        public function Setup() { }
        public function Base_Render_Before($Sender) {

    If all went well, you should see your 'this is my sweet new navbar!' text above your navbar.
