I´m using so:

{if(!is_empty(P1_1.NAOK == "SQ001"),"Option one","")}

hides the option , but the radio still visible button.

I hope you can help me

Regards!

That expression is wrong. You are checking if an option was not answered and are mixing this with checking for a variable value. That can't work.

In addition to that, you can't hide subquestions, that feature is not implemented yet (but may be at the next Limesurvey version).

Have a look at the array filter or array exclusion option instead.

You have to use and hack array filter.

Sorry : only in french : limesurvey.sondages.pro/676785.html

Thank you! Denis

It´s work Ok.

regards!
