   </li>
   <li>
     <app-category-menu-item></app-category-menu-item>
   </li>
   <li>
     <app-category-menu-item></app-category-menu-item>
   </li>
 </ul>

3. Replace the CSS file /src/app/modules/market/category-menu/category-menu.component.css contents with the following:

ul, li {
   list-style: none;
