title: How to add custom HTML to wp_nav_menu?
body: <p>I'm familiar with WordPress and using the WordPress menu system. But I'm looking for a way to add custom HTML to <code>wp_nav_menu()</code>.</p>
  
  <p>I'm trying to create a menu like this:
  <img src="https://i.stack.imgur.com/4VzFw.png" alt="enter image description here"></p>
  
  <p>Notice how the drop down menu under products contains an image and a link. I'd like to re-create this. I've looked at a few plugins, but would rather code it.</p>
  
  <p>I don't mind hard coding the image and link, but I'd like to keep the flexibility of using WordPress to manage the menus.</p>
