Hi Tom,
Can you explain the HTML? I am also working on a side-by-side question, but my answers are numeric text boxes instead of radio buttons. I would like hide and disable the certain text boxes under square feet column for vegetables crops grown in-field, Fruit trees,, Grapes, Other non-tree fruit, Nut crops, Some other specialty-type crops and Row crops. Thank you in advance.

Hi FJSandy the method that is being used here is applying CSS to just this survey page by including the CSS within the Question Text's HTML. To get the elements to add "display: none" to, I used the browser developer tools by previewing the unmodified question and hitting F12, navigating to the element, and then copying its selector, like in the below:

Tom,
Thank you for the detail explanation. I really appreciate your help. Thank you again.

Hi Tom,
In my original request for help, I forgot to mention that I am displaying crops that were selected in another question (carry forward). I am mentioning this because the above syntax works perfectly when all 10 crops are selected but not so well when I crop 1, crop 4, and crop 4 are selected. How can I modify the syntax to accommodate this wrench? Thank you in advance

Hi FJSandy , I don't think using "nth child" method will work for that. Instead, try going a level deeper and selecting the IDs of the text input elements. Update the below with the QID of your SBS question and then add it as Custom CSS in the Style section of your survey's Look & Feel.
#QR\\~QID6\\#2\\~x1\\~1\\~TEXT,
#QR\\~QID6\\#2\\~x3\\~1\\~TEXT,
#QR\\~QID6\\#2\\~x4\\~1\\~TEXT,
#QR\\~QID6\\#2\\~x5\\~1\\~TEXT,
#QR\\~QID6\\#2\\~x7\\~1\\~TEXT,
#QR\\~QID6\\#2\\~x8\\~1\\~TEXT,
#QR\\~QID6\\#2\\~x10\\~1\\~TEXT {
display: none;
}
