As a teacher, I can add a 'random question' to my quiz where the question is taken from a question category (optionally including sub categories) with optional filtering by tags.

The ‘add a random question’ dialog allows for:

• Selecting a question category;
• Specifying whether questions from sub categories should be included, and
• filtering of the random questions in the question bank by specifying a tag, either by entering free text or selecting tags from a drop down.
• If the search returns no results you will still be able to create a random question, but until new questions are added matching the search criteria, the quiz will display an error.
• You will no longer be able to add a new question category at the same time as creating a random question (there is not enough room to display a preview of the search as well as this create new question category option).
