 * A dropdown with a Kebab button, commonly used in Cockpit pages provided as
 * component so not all pages have to re-invent the wheel.
 *
 * 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
 * component.
