In Cockpit we currently have our own ContextMenu component , currently not really re-usable. Now that we are working on a plugin that also needs a ContextMenu, I've been thinking about making it re-usable.
In today's PF community meeting I noticed that the react-topology package also includes a contextmenu component.
Maybe it would be beneficial if that was moved here? I haven't looked into the re-usability of the react-topology's contextmenu for our use case but I can imagine there might be more projects using PF which could use it.
