• opts.width - menu width in columns
• opts.x - top-left corner x offset, default: 1
• opts.y - top-left corner y offset, default: 1

The menu can be driven around with the arrow keys, vi-style j/k, and emacs-style C-n/C-p.

menu.add(label, [handler]) or menu.add({ label, [line], [handler] })

It is also possible to pass the item in as object.

line is an optional property which contains the way how the line should be rendered. In case some advanced renderings are supposed to take place.
