 Mega menu
 =========
 
 A mega menu is a dropdown menu with additional possibilities and not just a list of links. In a
 mega menu, you can use any kind of content (text, images, icons, ...).
 
+In Odoo, you can select a mega-menu template in the list. If you don't need a custom layout, you
+can re-use the template structure in the `mega_menu_content` field like any static content.
