I have put the stage values in pageblocksection instead of columns for which i think you will need html. I have had to write a lot of redundant code which i am sure I could of done without...if you find a better solution please let me know and also for the rest of the pick list values you can simply copy paste the code making small changes..hope you get it . I hope a better developer in this board would be able to throw some light on how to do this as i found it quite a challenging code to write
