Hi Arlette, 

Thanks for reaching out to Jotform Support. You can easily hide a radio item on your online form by Injecting CSS Codes. Let me walk you through it:

1. First, copy this code:

#label_input_66_2 {

  display: none !important;

}

2. In Form Builder, click on the Paint Roller icon on the right side of the page to open Form Designer.

3. Now, in the Form Designer menu, click on the Styles tab, scroll down and paste the code into the Inject CSS Code box. That’s it. The code is automatically saved.

Take a look at the screenshot below to see how it works:Give it a try and let us know how it goes.
