# Code attribute set to multiple choice stays hidden

Asked by Andras on 2018-04-06

Dear OF Team,

I have a code attribute set to multiple choice and a simple expression defined for its relevancy.
When I tick the "Hide when not relevant" box, the field stays hidden regardless the result of the relevancy expression.
Could you check if this is a bug?
I have checked and this is happening in the preview, and working in Collect Mobile.

Thanks!
Andras

Hi Anrás,  
Can you double check the expression you use for the relevancy trigger? (define it in a boolean calculated attribute for example and see if it's value changes properly).  
Also, can you please tell us what kind of multiple attribute have you defined? Is it a code attribute?  
Many thanks,  
Open Foris Team

> Hi, The attribute is not a multiple one, it is a single code attribute. I want to allow the user to select multiple instances from the code list. The relevancy is defined using the previous code attribute (prev_att > 1). Relevancy works if I remove the tick for hiding the field. I.e. the field is grayed out. After testing, the relevancy works on a simple numeric attribute. It seems that the problem is with the multiple choice combined with hiding the attribute (if I remove the tick from Multiple and/or from the Hide when not relevant, the field works as expected).
