View source for Showing Answer Option in tab

== Showing answer option in tab == 
We have a single question which has a lot of answer options. We want to show answer options in Alphabetical tab  

[[Image:Tab20120116.png]]

== Solution == 
Using Java Script property of question.

There are 2 type of alphabetical tabs.

# '''No tab is selected as default'''
# '''An extra tab showing all answer options which is selected as default'''

== Code 1: No tab is selected by default == 
<source lang="javascript">
