	// Keys, when set, replace Shortcut with one keycap per entry (for example
	// "⌘", "⌥", "H"), painted with Kbd at the row's trailing edge.
	Keys []string
	// TrailingWidth reserves that much of the row's trailing edge for content the
	// caller paints itself (a switch, a badge, a small icon) with AddItemSlot and
	// BeginContent. Keys and Shortcut are not drawn when it is set.
	TrailingWidth float32
	Value         string

	// Icon, when it has any geometry, is painted before the label (after the
	// checkbox or radio indicator, if the item has one). A single-color icon takes
	// the item's text color; a multi-color one keeps its own.
