Custom functionality like Reorder.aspx

Hi All,

I want to have custom functionality like Reorder.aspx. When the order of a list box item is changed, it should automatically take care of the values of remaining list box.

Can this be done using Jquery or any custom coding.

We cannot use Reorder.aspx as we have a list of countries and cities and each city needs to be reordered.

List Schema 

Please help.

Thanks in Advance, Jiniv Thakkar
