 * isOpen/setIsOpen are optional -- you need to handle the state externally if you render the KebabDropdown in an
 * "unstable" environment such as a dynamic list. When not given, the dropdown will manage its own state.
 *
 * This component expects a list of (non-deprecated!) DropdownItem's, if you
 * require a separator between DropdownItem's use PatternFly's Divivder
