SilverStripe PHP Forms - If I nest a SelectionGroup inside a FieldGroup, one of the related SelectionGroup_Items' Radio Box does not show up. Why?

Question

You could add another fieldset then set it's attributes to id="hidden_field" aria-hidden="true". In the css document you could do the following.

    #hidden_field{
        display:none;
        height:0;
        width:0;
        margin:0;
        padding:0;
        visibility: hidden;
    }

This should hide SilverStripe Framework's query behavior. In my own php forms I had random brackets appearing whenever someone submitted a new form numerous times under different part-id numbers. I used this approach to hide the random brackets on my site.
