With Open Learner's the new H5P question bank tool you can create H5P from existing questions in your LMS question bank. Individual question can be individually be converted into a H5P content type that provides the same type of questions or multiple questions may be added as sub content to support content types that are designed to include those questions.
The H5P Content Type question format that has been developed on Open Learner, is now available to be installed plugin the Moodle plugin database directly on any Moodle 3.5+ site. This adds the ability to import files H5P content files directly into the question back on those systems. Questions that were contained in H5P content are then available to be included in quizzes and activities natively on those system.
