Can you elaborate your solution little more please. I have mentioned piece of
my code for ur reference. I have to change the background color of the
layer, when an event is triggered like if the option of a radio button
selected is 'Yes'. I am able to hide it by changing the state through java
script, Since there is a whitespace I either need to shrink and expand or
change the background color so that user will realize that the corresponding
question is disabled.
Your response to the same would be highly appreciated.
Thanks a lot
Swapna.
