Please don't use checkbook hacks for menu. When a lot of work can go into trying to make them accessible, it will be a lot easier and cleaner doing straight JavaScript. As it stands, you're missing a lot of ARIA for these components which isn't accessible and looks awful in TUI browsers with unusable checkbox elements scattered through the hierarchy. Further nitpick is using the `dd-` prefix for the inner dropdown bits; it's confusing because `<dd>` is already an HTML element.
