Image Radio Buttons Widget: how do I make 2 categories of radio buttons?

I would like to make 2 categories of radio buttons so the client can only pick one option between the two groups. This is currently set up as 2 widgets. How can I set it up so its once widget with a small header to separate the groups?

I have cloned your form, and managed to accomplish what you need by doing the following:

1) Putting all images in one widget.

2) Adding two extra images, with two extra image labels. 

So this would be the URLs to put in the image box:

And this would be the image labels to put in the widget:

Custodial,Electrical, Plumbing, Key and Lock, Temperature, Waste Management, Pest Control, Other, Service Request:, Cart Reservation, Painting, New Furniture/Relocation, Maintenance Request:, Cabling, Custodial, Electrical, Key and Lock, Pest Control, Plumbing, Screens, Temperature, Waste Management, Other

3) Finally, I created this custom CSS code to hide the extra images, and make the image labels look like "Category labels": https://www.jotform.com/help/428-How-to-Inject-CSS-Codes-to-Widgets 

ul#images_button_container li:nth-of-type(9){

display: block;

width: 140px !important;

}

ul#images_button_container li:nth-of-type(13){

display: block;

width: 190px !important;

}

#_d8,#_d12{

    display: none;

}

#_l8 span{

    color: #555 !important;

    font-family: Lucida Grande, sans-serif  !important;

    font-weight: bold  !important;

    font-size: 17px  !important;

   margin-left: -33px;

}

#_l12 span{

    color: #555 !important;

    font-family: Lucida Grande, sans-serif  !important;

    font-weight: bold  !important;

    font-size: 17px  !important;

   margin-left: -36px;

}

label span{

    font-size: 12px !important;

}

This is the result: https://form.jotform.com/80427976126968
