We come across the question quite often, if it is possible to display a hidden widget (text, HTML5) on students correctly answering a multiple choice question or another question type.
I know you can display a module or a page on a completion of another page, but is there a way to display ideally a text widget on the same module page if a student answers a quiz question correctly.
This means that initially, the text widget is hidden under the quiz widget, if the quiz question is answered correctly, the hidden widget is revealed underneath. 

It would be great if this worked with multiple quiz widgets and Submit button at the end to create a complex reveal scenario based on multiple answers.
