I'm using ZC 2.01 and Fluorspar 1.8

I'd like to add "New Products" and "Specials" to the dropdown menu under "Shop".

You can see it at https://zencart6.webdesign.place/

I've looked at tpl_mega_menu.php and believe this is the relevant section

Code:
          <ul class="mega-menu "><!-- bof mega-menu -->
               <li class="categories-li fullwidth"><a class="drop first_Item" href="#"><?php echo HEADER_TITLE_CATEGORIES; ?></a><!-- bof cateories    -->
                    <div class="dropdown_expand ">
                         <div class="levels">
                         <?php
                               // load the UL-generator class and produce the menu list dynamically from there
                               require_once (DIR_WS_CLASSES . 'categories_ul_generator.php');
                               $zen_CategoriesUL = new zen_categories_ul_generator;
                               $menulist = $zen_CategoriesUL->buildTree(true);
                               $menulist = str_replace('"level4"','"level5"',$menulist);
                               $menulist = str_replace('"level3"','"level4"',$menulist);
                               $menulist = str_replace('"level2"','"level3"',$menulist);
                               $menulist = str_replace('"level1"','"level2"',$menulist);
                               $menulist = str_replace('<li class="submenu">','<li class="submenu">',$menulist);
                               $menulist = str_replace("</li>\n</ul>\n</li>\n</ul>\n","</li>\n</ul>\n",$menulist);
                               echo $menulist;
                              ?>
                         </div>
                    </div>
               </li><!-- eof categories  -->

and I've looked at categories_ul_generator.php

but I can't work out where to put the items I want.

Thanks in advance!
