Code

//add a row before a sub question in the grid
//subQuestionIndex: the index of sub question which we should add a row before
//cssClass: the stylesheet that would be applied to the new row
//text: name of the sub question group
//includeAnswerOptionTexts: if it is true, answer option texts will be included in the new row
quest.addRowBefore = function(subQuestionIndex, cssClass, text, includeAnswerOptionTexts)
{ 
 //get number of columns 
 var n = $(".grid_inner")[0].rows[0].cells.length; 
 $(".grid_inner").find("tr").each( 
 function(i) 
 { 
 if (i == subQuestionIndex + 1) 
 { 
 if (!includeAnswerOptionTexts) 
 { 
 $(this).before( $("<tr>")
 .append($("<td colspan="+n+">").text(text).addClass(cssClass))
 ); 
 } 
 else 
 { 
 var tr = $("<tr>").append($("<td>").text(text).addClass(cssClass)); 
 for (var j=0; j<quest.questions[0].options.length; j++) 
 { 
 tr.append($("<td>").text(quest.questions[0].options[j].text).addClass(cssClass)); 
 } 
 $(this).before(tr); 
 } 
 } 
 } 
 )
}

quest.onInit = function()
{ 
 //insert a cell before Don't know on header 
 var dontKnow_value = 3; 
 this.addRowBefore(2, "extra_row_header", "Alcohol drinks", true);
}
