Adding a link to the navigation menu of an AppGini application in a way that works with both the vertical and horizontal menus. Add the following code to the generated `hooks/footer-extras.php` file.

footer-extras.php

<script>$j(() => {
   // append the link to the horizontal menu
   $j('.horizontal-navlinks').append(`
      <ul class="nav navbar-nav">
          <a class="btn btn-default navbar-btn" href="https://example.com">Example link</a>
      </ul>
   `);

   // append the link to the vertical menu
   $j('.vertical-nav .panel-group').append(`
      <a class="btn btn-default btn-block tspacer-lg" href="https://example.com">Example link</a>
   `);
})</script>

This is not the recommended method for adding links to your AppGini app's navigation menus. We prefer using hooks/links-navmenu.php. But in case you want more control over the link appearance, you can customize the above code and add it to hooks/footer-extras.php.
