This topic sounds really interesting but it is quite difficult to follow the idea&nbsp;:-S. 

I can see that there are 2 questions in this sample: "Brands" and "Q7" which Q7 is the main question and&nbsp;Brands is used for storing products list. (I just guess) 

I tried&nbsp;it with a text grid question named "Q7", paste the script above to "Language dependent" field (just try re-format the script after pasting). 

Every thing is okey now, I start opening a new tested&nbsp;RPQ in interview manager page.&nbsp;The question Brands looks fine but unfortunately, after anwser it, my anwsers will be put into the left column of question Q7 and I got a&lt;span id="fck_dom_range_temp_1231494683803_17" /&gt; javascript error.

"Object does not support this property and method" for 

//configure the drag move <br>$(".draggable_text").draggable( <br>{<br>mouse: "pointer",<br>helper: 'clone'<br>} <br>); 

<br>

I am not sure that I did a right thing, please help me investigate it if you have time. Thank you very much in advance
