Both horizontal and vertical single grid
Chalenge :
There are a single grid question . Respondents should prioritize statements (sub questions) .
Example :
I have a list of trade-mark and want the user to prioritize those list :
Dell
Apple
IBM
FPT Elead
Solution :
Use single grid question (statements as subquestion and ranks as answer option )
Code
The script makes a single grid question function as a single grid both horizontally and vertically.
option.prototype.getHTML = function(ltype) {
var stmp = "";
if(this.visible) {

if(this.disabled) stmp += "disabled ";
stmp += "onclick=\"myoptclick('"+this.label+"',"+this.index+",false);\">";
return "<td valign=\"center\" align=\""+this.align+"\">"+stmp+"</td>";;
break;
