I have a main menu with main menu items and standard sub-menu items.The sub-menu items display when i hover over the main menu items as they should. I would then like a HTML block to display when I hover over the individual sub-menu items.
Your theme provides this option, however when it’s configured it does not display the HTML block.
I have tested the HTML block in question by setting it to display when I hover over a main menu item and it works fine.
HTML block appears only in main menu item. It would not appear on sub-menu. It means you can either configure your menu in the way of menu-sub-menu or menu-HTML block as a submenu.
