QS:Exclusive option

Description

The exclusive option attribute takes the code of an answer in a multiple option question so that when clicked on the its corresponding checkbox, all the other previously checked options will get unchecked and get marked as read-only (=disabled). This function was created to ensure data integrity when one of the multiple options in a multiple option question implies that no other option can be selected too. Basically, this feature marks the other attributes as being irrelevant.

It is also possible to have multiple exclusive options. These must be separated by semicolons.

Example
