This WYSIWYG Web Builder extension is a multi-level panel menu with Font Awesome icon support. Besides the standard links there is also a dedicated section for social icons. Unlike other panel menus which are usually triggered by a hamburger button, this menu displays a vertical bar at the left or right side of the page. Moving the mouse over the bar will expand the menu.
