Hide and show fields when dropdown list is changed

I have a page layout containing fileds from custom object and I need to show or hide certain fields on this page layout based on the selection of the drop down list.
 
Is there a way I can assign a trigger to my drop down list to triggere some code tha will go through my fields and hide them?
 
I would really appreciate if someone gives some insights and pointers on that request.
 
Thank you.
