Apply if condition on embedded data and use below code in to hide second column:
jQuery("#"+this.questionId+" .SBS2").css("visibility","collapse")

Thanks Rondev. I'm quite new JS, are you able to provide a bit more of what the code would look like? Eg do i need to add var for the embedded data field?

if("${e://Field/ED1}"=="1"){
jQuery("#"+this.questionId+" .SBS2").css("visibility","collapse")

}

Thank you Rondev

What would the class name be for a text entry question? I'm trying to do the same for a text entry question and hide the first row but i assume SBS2 can only be used side-by-side?
would it be
if("${e://Field/ED1}"=="1"){
jQuery("#"+this.questionId+" .TE1").css("visibility","collapse")

https://www.qualtrics.com/community/discussion/comment/30033#Comment_30033Are you using text entry question of type form?

Yes, text entry of type form - with two fields.

https://www.qualtrics.com/community/discussion/comment/30037#Comment_30037For this we do not need JS, you can directly add display logic using answer choice display logic

Thanks rondev
