Multiple Select options

Hi,

I have a requirement where i have to use to separate select options but the value of the 2nd Select option is dependant of the value chosen in the first select option.

For eg:First Select option is for SWCV and 2nd option is for Data Object.

If you choose S1 as SWCV in first select option then the values in select options for Data object should be populated for Data objects belonging to SWCV "S1" only an not for any other SWCV.

PS:Points will be awarded
