Show field options based on selected value in another field

[Fariz Aliverdiyev]

Good day. 

There are 2 custom fields: Field1 with options "option1" and "option2", and Field2 with options "option3" and "option4". So, I would like to make available only "option3" value for Field2 if "option1" value is selected for Field1 on a transtition screen. I know, that this can be done with behaviours, but I'am new in Groovy. Is there any example script for my case? 

Thank you in advance.
