How to add an iQuest
First design a question in the usual way and then click on Specify on the Interactive element.
Once Specify has been clicked a new window appears where you can select the iQuest to use. At the top of the new window is a Dropdown box where you make your selection. The list will only include iQuests that are suitable for the type of the current question e.g iQuests that work with a Single Choice Grid Question.
Once you have selected the iQuest the options will be displayed. The options are grouped together in sections that refer to similar styling or functionality within the question.
