resource manager schedules 1 batch particular center week @ once, comes down schedule next batch other center same week.

at time of scheduling batch there dropdownlists batches, centers,skills , faculties. resource manager selects each values dropdownlists.

conditions implement page :

1. in row : each skill dropdown should not contain skill scheduled in of previous date same batch.

2. in column : each batch dropdownlist should not contain scheduled batches.

3. in column : each faculty dropdown should not contain same faculty occupied same date , time.

now confused how implement page can able render , fill each dropdown appropriate values. should use handlers fill dropdownlist dynamically or other jquery/javascript ideas implement this. thankful if sort out.

thanks, aarti

the best option fire validations constraints require upon submit.

any ways or else if have decided make page dynamic, suggest use javascript/jquery. using handlers make page take more time on rendering response on each select.

here jquery example closer need.
