APEX

hi,

i am using Application Express 3.1.2.00.02 and got a question that how to enable or disable items according to condition?

I created a form based on table/views and have number of fields so first few fields are pre-populated and one field (code) will decide, which fields are goind to be inserted? If codes are 1 and 2 then fields related to first table will be inserted and second table fields should be disable or grayed out and same if codes are between 3 and 7 then second tables fields should be inserted and first table columns should be disable / grayed ot.

Please reply if anyone know the solution?

Kind regards,
