Need help in Jqury Sortable

Hi,
I am new in Jquery.
I want to use sortableUI to my datalist. Each row in datalist contains
text with serial number. I have used sortable ui successfully. But now
I want move the text not the serial number while sorting.
For example:
1. A
2. B
3. C
I want to sort items A,B or C..But not the Serial no.
Any suggestions?
Thanks in advance.
