The import menu is no more present in latest versions of idea. Old import code is not registered anymore.
An implementation of https://plugins.jetbrains.com/docs/intellij/external-system-integration.html is needed for dune, but it’s lot of code.

I remember why there is no more SDK, it is related to #365 . SDK is only available in intellij flavor editors and not in other like webstorm.
When you open a ml file, there is a top banner with a link to setup opam in settings.

import has been updated.
when opening/importing a dune project, directories that contains a dune file are recognized has source directories.
also, when importing from sources, you can define the opam/switch during the import process
