Class Method Details

.show(menu, user, **options) ⇒ Object

Accepted options:

:if - only include this menu item if the provided block returns true when passed the current user (if not present, item is always included) :include_icon - if true, include a FontAwesome icon (no fa- prefix) as specified by the ‘icon` property in the menu’s YAML (default false) :include_ul - if true, wrap the dropdown <li> list in a <ul> (default true)

With :include_icon, you still need to include FontAwesome yourself. With :include_ul, you still need to add the dropdown’s trigger yourself.
