Grey out checkboxes

Question

Hi!

I have just a simple select question with checkboxes with seven responses plus a a "none of the above" at the end (so eight list members). I'd like to grey out the seven responses if the "none" option is chosen (purely as a visual thing - of course I know I can simply make the None exclusive!). I have really very little experience in javascript, so was wondering if someone can help.

Thanks!

Great Idea!

But the thing is if the respondent can change his mind for selection, at that time this grey wont be work, i suppose it should check the options when we select the radio button gets exclusive, and vice versa cases, please try the below code:


<script type="text/javascript">
var a=0;
var b=0;
for(i=0;i<=4;i++)
{
    if(SSI_GetValue("Q7_r1_"+i)==1)
    {
        a=a+1;
    }
}
function SSI_CustomGraphicalCheckbox(GraphicalCheckboxObj, InputObj,blnCheck)
{
    b=0;
   
    if(blnCheck == true)
    {
        SSI_RadioReset("Q7_c1");
        a=a+1;
        b=0;
    }
    else
    {
        a=a-1;
        b=0;
    }
}
function SSI_CustomGraphicalRadiobox(GraphicalRadioboxObj, InputObj)
{
   
    if(InputObj.name == "Q7_c1")
    {
       
        SSI_SetSelect("Q7_r1_1", false);
        SSI_SetSelect("Q7_r1_2", false);
        SSI_SetSelect("Q7_r1_3", false);
        SSI_SetSelect("Q7_r1_4", false);
        a=0;
        b=1;
        //alert(a+","+b);       
    }
}
</script>
