### Description

Customizable menu that provides for implementing interactive items, subitems, and icons pulled from `box-ui-elements`. Icons take the form of those in `/icons` for this feature.

Responsive states exist for large, medium and small. To override the medium state, add an `is-forced-open` class to the container element.

Remove the menu item from favorites to see the placeholder text.
