Setting up a Mega Menu for your header
A Mega Menu is a stylized submenu that allows you to also add an image to your navigation. It can be used to put more links together and group them in a form of subcategories.
To add a new Mega Menu you need to click on the Header section arrow to expand it after which click on 'Add image'.
Setting up the Mega Menu can be done by accessing the block settings.
Here you will find the option to add it under any first-level link in your header as well as the options to add the image.
To get a list of links like the one from our demo you'll need to simply set them up from your navigation menu as standard drop-down menus.
You can learn more about this in Shopify's great articles on the topic.
