Mega menus are a new trend. These are drop-down triggered when an event is triggered by hovering over a link mentioned in the menu. This is used to show all options under the particular menu. This is used on e-commerce site where all the available options are listed under a particular category. To add mega menu we are using “mega-dropdown menu”, to the menu item which will display the items under its list. To separate the content we are using the tab classes like “tab-content” and “tab-pane”. Define the tab-pane with particular ID’s. Define the nav tab’s as toggleable with links to the tab-pane of mega-menu items. Check out the CSS for hovering and styling. As mega menus are dropdowns using hovering events, you must be careful to add this on the selected menu items. Use this for your e-commerce website by listing your items and images.
