Hi,

I have a single choice question like this.

Maruti
BMW
Hyundai
Honda
Audi

But client want to show Maruti and BMW only for US country. Can anyone help me how to hide those 2 codes for other countries?

There is no direct answer relevance for single choice questions so you have two options...

1) Create a separate question for the US.

2) Insert a hidden multiple-choice question. Toggle the checkboxes in that question with a hidden equation question. Place an array filter on your single-choice, based on the hidden multi-choice. Search the forums - Joffm has given many example of this method.

In this case I'd recommend to set the default answers of the hidden multiple question to "checked".
Then you have only two assignments to uncheck "Maruti" and "BMW" if country=="US".
Something like
{M1_1=if(country=="US","","Y"}

As far as I understood you want to uncheck if country is NOT =="US".

Oh, so sorry,
it takes too much time between reading and writing something.

Of course it has to be:
{M1_1=if(country=="US","Y",""} because you want to display these brands only if country is "US".
