Hello, can anyone help me please.
I'm looking for a code that when I change a value from the picklist in the same time it will appear a field on the vfpage without saving yet.
I created a vfpage that has 3 picklist with field dependencies.
and I want to know if :
For example:
If the picklist Series = 001-001
the field #Pre_Impreso_001_001__c has to appear on the vfpage and
the field #Pre_Impreso_002_001__c has to desappear
and
If the picklist Series = 001-002
the field #Pre_Impreso_001_001__c has to desappear of the vfpage and
the field #Pre_Impreso_002_001__c has to appear

Is it posible to do that?
