a separator, or a submenu parent containing children.

// Nil for separators and submenu parents.
OnAction func()
// Disabled prevents this item from being activated.
Disabled bool
// Children holds submenu items. If non-empty, this item opens a submenu
// on hover instead of invoking OnAction.
Children []MenuItem
// isSeparator marks this item as a horizontal separator line.
isSeparator bool
